The American Quarterly Review, No. 17, March 1831 Cells whose chemical actions are reversible are called "storage" or "secondary" cells. The Automobile Storage Battery Its Care And Repair In the case of chemical action, for instance, the particles separate and form new combinations, often with a great visible disturbance of the mass. A System Of Logic, Ratiocinative And Inductive On the whole, however, tungsten minerals are very resistant to weathering, and in all their deposits secondary concentration by chemical action at the surface has not played any appreciable part. The Economic Aspect of Geology This trough is silver plated inside, because most metals in common use would spoil the emulsion by chemical action. Scientific American Supplement, No. 647, May 26, 1888 Neither could chemical action have had any great agency in establishing the present temperature of the earth. The American Quarterly Review, No. 17, March 1831 The substances to be considered in the chemical actions are sulphuric acid, water, pure lead, lead sulphate, and lead peroxide. The Automobile Storage Battery Its Care And Repair Thus it is now thought that in the production of heat by friction, percussion, chemical action, etc., the ultimate source is one and the same. A System Of Logic, Ratiocinative And Inductive Sandstone, which forms wherever moving water or wind has collected sands, and pressure or chemical action has cemented them, is usually buff, but sometimes is brilliantly colored. The Book of the National Parks "They affect chemical action, retarding it greatly in exothermic actions, speeding greatly endothermic actions," answered X-6221, the greatest of the chemist-investigators. The Last Evolution In the ordinary manufacture of superphosphate, however, this is not considered necessary, as the heat developed by the chemical action between the phosphate and the acid is sufficiently great. Manures and the principles of manuring If none of the substances resulting from the original chemical action have been lost as gases, it may be possible to reverse the entire set of operations which have taken place. The Automobile Storage Battery Its Care And Repair To produce a bonfire, there must not only be fuel, and air, and a spark, which are collocations, but chemical action between the air and the materials, which is a force. A System Of Logic, Ratiocinative And Inductive Originally they were the washings of distant highlands brought down by rivers; the coloring of the shales and sandstones is that of the parent rock modified, no doubt, by chemical action in sea-water. The Book of the National Parks A storage battery, or accumulator is a device in which a chemical action is set up when an electric current is passed through it. Electricity for the farm Light, heat and power by inexpensive methods from the water wheel or farm engine But more important probably than even its mechanical action is the chemical action of lime. Manures and the principles of manuring In these cells it is often impossible, and always unsatisfactory to reverse the chemical action as explained above. The Automobile Storage Battery Its Care And Repair No doubt both processes occur; but in plants the odorous bodies are built up entirely by the chemical action of the plant itself upon simple salts of carbonic acid, ammonia and nitrates. More Science From an Easy Chair Then by chemical action on the coral beds and on the rocks, he created a dense cloud and caused it to form over the lake, thus in a measure protecting it from the sun's rays. Omega, the Man Such a battery will discharge nearly as much current as is required originally to bring about the first chemical action. Electricity for the farm Light, heat and power by inexpensive methods from the water wheel or farm engine Those may be divided into two classes—those accounting for it as due to physical properties of the soil; and those, on the other hand, explaining it as due to chemical action. Manures and the principles of manuring How this is done, and what the chemical actions within the cell are, are described in Chapter 4. The Automobile Storage Battery Its Care And Repair These, as perfumes and unguents, really served, not merely to gratify the olfactory sense, but to destroy by their chemical action the germs of disease. More Science From an Easy Chair An excess of tin will be marked by lines or pits in the filling, showing where the tin has been disintegrated or dissolved by the chemical action which occurs on the surface exposed to moisture. Tin Foil and Its Combinations for Filling Teeth The constant application of alcohol to the tissues of the body alters them gradually by its chemical action. Alcohol: A Dangerous and Unnecessary Medicine, How and Why What Medical Writers Say Plants in such a soil are apt to sicken and die, the water becomes stagnant, and certain chemical actions are caused which give rise to poisonous gases, such as sulphuretted hydrogen, &c. Manures and the principles of manuring During discharge, the chemical action also begins at the surface of the plates and gradually moves inward. The Automobile Storage Battery Its Care And Repair Its chemical action is such that it turns any oil or grease into soap, which is easily washed out with clear cold water. One Thousand Secrets of Wise and Rich Men Revealed Thus it might, and perhaps will, be discovered, that in the production of heat by friction, percussion, chemical action, &c., the ultimate source is one and the same. A System Of Logic, Ratiocinative And Inductive (Vol. 1 of 2) At Death the higher principles, or Triad, lives on, while the lower principles of Quarternary dissolve and separate from each other and finally disintegrate, along the lines of a process resembling chemical action. Reincarnation and the Law of Karma A Study of the Old-New World-Doctrine of Rebirth, and Spiritual Cause and Effect If, therefore, sulphate of ammonia be heated above the boiling-point of water, or brought in contact with any other substance which will give rise to chemical action, it is easily decomposed. Manures and the principles of manuring The amount of energy which can be delivered by the battery depends on the amount of active material, sulphuric acid, and water which enter into the chemical actions of the cell. The Automobile Storage Battery Its Care And Repair There are two ways in which carbonate of lime may exert a chemical action on the organic matters of peat. Peat and its Uses as Fertilizer and Fuel It is, therefore, upon such substances that the self-propagating power of chemical action is likely to exert itself in the most marked manner. A System Of Logic, Ratiocinative And Inductive (Vol. 1 of 2) The source of the electricity in the voltaic instrument is due almost entirely to chemical action. The World's Greatest Books — Volume 15 — Science The exact nature of the chemical action taking place is a point of some dubiety. Manures and the principles of manuring As these chemical actions take place, sulphuric acid is used up, and hence there must be enough acid contained in the electrolyte to enter into the chemical actions. The Automobile Storage Battery Its Care And Repair In many cases peat requires some preparation by weathering, or by chemical action—"fermentation"—induced by decomposing animal matters or by alkalies. Peat and its Uses as Fertilizer and Fuel “A little leaven,” that is, dough in a certain state of chemical action, impresses a similar chemical action upon “the whole lump.” A System Of Logic, Ratiocinative And Inductive (Vol. 1 of 2) If the chemical action be impeded, the vital phenomena must take new forms. The World's Greatest Books — Volume 15 — Science The reason of this is, that a chemical action is apt to ensue, resulting in the loss of the nitric acid in the nitrate of soda. Manures and the principles of manuring These are called the "active" materials, because it is by the chemical action between them and the sulphuric acid that the electricity is produced. The Automobile Storage Battery Its Care And Repair When chemical action ceases, the liquid remaining is called reduced acid. Elements of Plumbing Dr. Liebig believes himself to have found the solution of this vexata quæstio in a class of chemical actions in which scarcely any less acute and penetrating inquirer would have thought of looking for it. A System Of Logic, Ratiocinative And Inductive (Vol. 1 of 2) No body will act chemically upon another body at any sensible distance; apparent contact is necessary for chemical action. The World's Greatest Books — Volume 15 — Science They may be said to possess both a mechanical and chemical action when applied to the soil. Manures and the principles of manuring This change due to the chemical action may result in the formation of gases, or of solid compounds. The Automobile Storage Battery Its Care And Repair These upper regions, hidden in an almost perpetual gloom, were decorated in monochrome by Sir James Thornhill; but his work has failed to resist the chemical action of the surcharged atmosphere. Bell's Cathedrals: The Cathedral Church of Saint Paul An Account of the Old and New Buildings with a Short Historical Sketch They may, however, exert a chemical action on the soil, altogether independent of their absorption by the plant, but its nature and amount are still to determine. Elements of Agricultural Chemistry The primary causes of the volcano and the earthquake are to a great extent the same, and connected with the development of heat and chemical action at various depths in the interior of the globe. The World's Greatest Books — Volume 15 — Science Hence it is that chemical action is the consequence of a power, without which it could never ensue, and with which it always acts in unison. James Cutbush An American Chemist, 1788-1823 Sending a current through a discharged cell, so as to reverse the chemical actions which brought about the discharged conditions, is called "charging" the cell. The Automobile Storage Battery Its Care And Repair When we speak of chemical action we look to a definite source for that action, and we do not say that such action is produced by chemical waves, but rather by electricity. Aether and Gravitation By it the Contact Theory, pure and simple, was totally overthrown, and the necessity of chemical action to the maintenance of the current demonstrated. Fragments of science, V. 1-2 Or, if we adopt the atomic theory or phraseology, then the atoms of bodies which are equivalent to each other in their ordinary chemical action have equal quantities of electricity naturally associated with them. The World's Greatest Books — Volume 15 — Science In the first experiment there is an instance of chemical action, as well as of single affinity, for the sulphur and mercury would remain separate if heat was not applied. James Cutbush An American Chemist, 1788-1823 It may then be "charged" again, and so on, the chemical action in one case causing a flow of current, and a reversed flow of current causing reversed chemical actions. The Automobile Storage Battery Its Care And Repair The chemical actions giving rise to the formation of the metallic ferrocyanide, of which the image consists, are quite complicated. Photographic Reproduction Processes It has hitherto been my aim to render the chemical action of light upon vapours visible. Fragments of science, V. 1-2 Admitting, however, that chemical action is the source of electricity, what an infinitely small fraction of that which is active do we obtain and employ in our voltaic batteries! The World's Greatest Books — Volume 15 — Science In cases where there is virus to be destroyed, or abnormal growths to be removed, we also secure the chemical action appropriate to these ends by the proper selection of our current. A Newly Discovered System of Electrical Medication When batteries are "dry" no chemical action can take place, and the battery does not deteriorate, while in a "wet" battery, chemical action takes place which gradually causes a battery to deteriorate. The Automobile Storage Battery Its Care And Repair The chemical colors are in general of mineral origin, produced by the action of one chemical upon the other, or in some cases by physical or chemical action upon earths and ores. The Building of a Book A Series of Practical Articles Written by Experts in the Various Departments of Book Making and Distributing When the quantity of nitrite vapour is considerable, and the light intense, the chemical action is exceedingly rapid, the particles precipitated being so large as to whiten the luminous beam. Fragments of science, V. 1-2 Materials that should not be Combined.—The advocate of factory-mixed goods warns the farmer against the danger of making combinations of materials that will cause loss by chemical action. Crops and Methods for Soil Improvement The other three, being Faradaic or induction currents, and having no perceptibly chemical action, are used where only change of electro-vital polarization is required. A Newly Discovered System of Electrical Medication In any lead acid battery current is produced by a chemical action between the active material in the plates and the water and sulphuric acid in the electrolyte. The Automobile Storage Battery Its Care And Repair This, I have been told, was due to the fever ferment in the blood and tissues developing unchecked, and its products setting up strong chemical action. Reminiscences of a South African Pioneer In the anterior portions of the tube a powerful sifting of the beam by the vapour occurs, which diminishes the chemical action in the posterior portions. Fragments of science, V. 1-2 Its value does not lie chiefly in physical action as an absorbent, but the beneficial results come through chemical action. Crops and Methods for Soil Improvement The chemical action has disturbed the omnipresent force of electricity, and a vigorous electric current is in motion. Blackwood's Edinburgh Magazine, Volume 61, No. 379, May, 1847 During this process a certain amount of chemical action often occurs leading to the brass surface exhibiting some discoloration.

The Western United States A Geographical Reader The Photographer's Plate.—It is known that the chemical action of an object on a photographer's plate is due to vibration; each represents a force of different intensity, hence the varying shades produced. Practical Mechanics for Boys Some scientists thought all life had grown by accident; the right combination of circumstances had occurred and a chemical action had followed. The Whispering Spheres What may be its chemical action there, is a question for us to attend to as we proceed. An Investigation into the Nature of Black Phthisis or Ulceration Induced by Carbonaceous Accumulation in the Lungs of Coal Miners The agitation being complete, chemical action takes place with the generation of heat, and finally results in the saponification of the fats. The Handbook of Soap Manufacture Now, when the atoms of a substance are disturbed by friction, or by chemical action, they get into a state of violent commotion, and try wildly to fly from, or to, each other. The Battery and the Boiler Adventures in Laying of Submarine Electric Cables Don't you know the well and favorably known chemical action of absence on young and juicy hearts? Play the Game! If the spheres are mixtures of energies, like we are mixtures of chemicals, death means extinction, just as biological death means the extinction of the chemical action in our lives.

Notes and Queries, Number 179, April 2, 1853. A Medium of Inter-communication for Literary Men, Artists, Antiquaries, Genealogists, etc Intensified yells all round told that chemical action had not been applied in vain, while the pirates who had gained the bulwarks were met with streams of boiling water in their faces. The Battery and the Boiler Adventures in Laying of Submarine Electric Cables We see, too, why colours mixed deteriorate each other, which they do more—in many cases—by imperfectly neutralizing or subduing each other chromatically, than by any chemical action. Field's Chromatography or Treatise on Colours and Pigments as Used by Artists The chemical action of the sun's rays is destructive to the organic material which makes up the composition of many of these organisms, while higher forms of organic life are stirred into activity by it. Human Foods and Their Nutritive Value The temperature reached in a given chemical action, such as oxidation, depends upon the rate at which the reaction takes place.

Handwork in Wood Light has a chemical action and tends to stimulate animal metabolism. Vitality Supreme It is the chemical action and interaction of elements—and the mind which measures and combines them; it is the physical action and interaction of force—and the mind which directs the process. Modern Religious Cults and Movements How could the chemical actions of dead matter infuse vitality into the first germ, or bud of a plant? Fables of Infidelity and Facts of Faith Being an Examination of the Evidences of Infidelity For this reason, when pure zinc is used in the preparation of hydrogen a few drops of platinum chloride are often added to the solution to assist the chemical action. An Elementary Study of Chemistry It is, for instance, difficult to see how this very quick visual process could be due to a comparatively slow chemical action, consisting of the destructive breaking-down of the tissue, followed by its renovation. Response in the Living and Non-Living There is first a chemical action in which the insoluble are changed into soluble substances, and this is followed immediately by the dissolving action of water. Physiology and Hygiene for Secondary Schools This abnormal heat, due to chemical action in the cement, soon passed away, and, with the approach of winter, the contraction of the concrete resulted in transverse cracks.

The Relations Between Religion and Science Eight Lectures Preached Before the University of Oxford in the Year 1884 His whole system of philosophy is nothing more nor less than the result of the liberation of certain forces produced by chemical action in the brain. Fashionable Philosophy and Other Sketches This is the simplest kind of chemical action. An Elementary Study of Chemistry They tell us it is one by which complex substances are decomposed into simpler forms, as some suppose, by chemical action; others, by development of fungi, different in different substances. Chambers's Edinburgh Journal, No. 426 Volume 17, New Series, February 28, 1852 At first he believed that mere contact was sufficient, but when, later, it was shown that chemical action took place, rapid progress was made in the construction of voltaic cells. Artificial Light Its Influence upon Civilization There are currents produced by chemical action called voltaic currents; by the action of heat, or thermo-electric currents; by the motion of magnets, or magneto-electric currents.

It compels us to regard with doubt the role of oxidation or other chemical action as essential, but rather points to the view that such effects must be secondary or subsidiary. The Birth-Time of the World and Other Scientific Essays When sodium nitrate is treated with concentrated cold sulphuric acid, no chemical action seems to take place. An Elementary Study of Chemistry His three great principles, indeed, were drilling, reduction of seed, and absence of weeds, and he saw that dung was a great carrier of the latter but lacked a due appreciation of its chemical action. A Short History of English Agriculture Hundreds of common materials like glass, rubber, iron, aluminum, etc., are manufactured by processes which involve chemical action caused by heat. General Science The life of the negative plates will be very considerable, because no chemical action is going on in the negative plate.

Cyclopedia of Telephony & Telegraphy Vol. 1 A General Reference Work on Telephony, etc. etc. The distinction between the cause producing chemical action and the circumstances favoring it must be clearly made. An Elementary Study of Chemistry Or, if we start with magnetism, this may give rise to electricity, and this again to heat, chemical action, and light. The Atlantic Monthly, Volume 13, No. 78, April, 1864 Evidently, the source of the current is the chemical action between the zinc and the liquid. General Science The force communicated to a magnet of this kind, which is often immense, is the product of the chemical action which goes on in the battery, and, in a certain sense, the measure of it. Lectures on Popular and Scientific Subjects The chemical action taking place within the LeClanché cell is, briefly, as follows: Sal ammoniac is chemically known as chloride of ammonium and is a combination of chlorine and ammonia. Cyclopedia of Telephony & Telegraphy Vol. 1 A General Reference Work on Telephony, etc. etc. The only exceptions are rare cases in which such active chemical changes take place in the dead body that heat is generated by chemical action. Disease and Its Causes For it to be produced spontaneously, it would appear that there must exist simultaneously a rather high temperature and a chemical action in the gas. The New Physics and Its Evolution In this case, chemical action is expended in heat rather than in the production of electricity and the liquid becomes hot. General Science When X-Rays are driven into a patient's body electrons are set in motion within, and moving over certain minute distances, initiate chemical actions which are necessary to some cure. Recent Developments in European Thought This uses practically the same materials and has the same chemical action as the old disk LeClanché cell shown in Fig. Cyclopedia of Telephony & Telegraphy Vol. 1 A General Reference Work on Telephony, etc. etc. Being thus arranged, there was no chemical action whilst the plates were not connected.

Life in a Thousand Worlds If fresh liquid is poured into the vessel so that the chemical action of the acid on the zinc is renewed, the current again flows. General Science Thus, the chemical actions which result when ice and salt are mixed cause a withdrawal of heat, and a "freezing mixture" is formed. Lippincott's Magazine of Popular Literature and Science Volume 15, No. 86, February, 1875 It is essential to the operation of these cells that they shall be moist within, and when such moisture is dissipated the cell is no longer usable, as there is no further useful chemical action.

Life in a Thousand Worlds The method of exhibiting the action of the ultraviolet rays by their chemical action has been long known; indeed, Thomas Young photographed the ultra-violet rings of Newton. Six Lectures on Light Delivered In The United States In 1872-1873 If tin cans bulge at both ends after they have been completely cooled, it indicates that they are spoiling and developing gas, due to bacteria spores or chemical action. Every Step in Canning To preserve the wood it is generally treated with creosote, which, in contact with the lead cover of the cable, sets up a chemical action, resulting in the destruction of the lead. Scientific American Supplement, No. 821, September 26, 1891 I find that the power is not only greater on the instant, but also that the sum of transferable power, in relation to the whole sum of chemical action at the plates, is much increased. Experimental Researches in Electricity, Volume 1 They live, in part, on the chemical action produced by fire breathing. Life in a Thousand Worlds The general relation of colour to chemical action is worthy of the application of the method by which Dr. Draper proved so conclusively the chemical potency of the yellow rays of the sun. Six Lectures on Light Delivered In The United States In 1872-1873 They are not three things, but three aspects of one thing, just as a sunbeam might be regarded either as the source of warmth, or of light, or of chemical action. Expositions of Holy Scripture: Romans Corinthians (To II Corinthians, Chap. V) There are, of course, many localities where, if the cable is laid in contact with the earth, a chemical action would take place which might result in the destruction of the cable. Scientific American Supplement, No. 821, September 26, 1891 These, however, I expect to prove, are all secondary results; the mere consequence of chemical action, and no proofs either of the attraction or of the law announced respecting their places173.

Murder in Any Degree The latter is a good test, for paving for stables must be non-slippery and have good power of resisting chemical action. Scientific American Supplement, No. 530, February 27, 1886 The electrodes employed in electro-analysis are almost exclusively of platinum, since that metal alone satisfactorily resists chemical action of the electrolytes, and can be dried and weighed without change in composition. An Introductory Course of Quantitative Chemical Analysis With Explanatory Notes This makes it possible to place another original on the pad immediately without waiting for the ink to vanish by chemical action as in the original hectograph. The Boy Mechanic: Volume 1 700 Things for Boys to Do After the first experimental investigations to establish the definite chemical action of electricity, I have not hesitated to apply the more strict results of chemical analysis to correct the numbers obtained as electrolytic results.

The Nuttall Encyclopædia Being a Concise and Comprehensive Dictionary of General Knowledge The breaking down of the cell walls through the chemical action of so-called "enzymes" secreted by the fungi follows, and the eventual product is a rotten, moist substance crumbling readily under the slightest pressure. The Mechanical Properties of Wood Including a Discussion of the Factors Affecting the Mechanical Properties, and Methods of Timber Testing Fuels.—Artificial heat is commonly produced by combustion, caused by the chemical action of the oxygen of the air upon the hydrogen and carbon found in fuel. Science in the Kitchen. I have no hesitation in saying, that this is a kind of black sandstone, often found at the bases of most cliffy points, and probably coloured by the chemical action of the saltwater.

Here for a while I must leave the consideration of the definite chemical action of electricity. Experimental Researches in Electricity, Volume 1 When we apply fire, the chemical actions commence and the usual effects follow. The Atlantic Monthly, Volume 09, No. 55, May, 1862 Remember, combustion is a chemical action, and when a chemist wishes to act on a solid easily, he always pulverizes it as a first step.

The Second Generation Chemical decomposition.—The chemical action of voltaic electricity is characteristic of that agent, but not more characteristic than are the laws under which the bodies evolved by decomposition arrange themselves at the poles. Experimental Researches in Electricity, Volume 1 We cannot call it chemical action, and dismiss the thought, and neglect further inquiry, unless we would place ourselves with those who regard the movement of the steamboat as being due to the machinery. The Atlantic Monthly, Volume 09, No. 55, May, 1862 Electricity, the great moving power in all chemical actions, shared the fate of chemistry in general, and met with condemnation without trial.

The Devil's Dictionary A great deal of chemical action then commences, salts of various kinds effloresce on the surface, and the mass becomes hard. The Voyage of the Beagle The plates are prepared and "formed" in various ways, and the chemical actions are similar to those above stated, the positive plate being oxidized and the negative reduced during "charge," and reversed during "discharge." Edison, His Life and Inventions The increase of intensity or power of the current produced by a simple voltaic circle, with the increase of the force of the chemical action at the exciting place, is here sufficiently evident. Experimental Researches in Electricity, Volume 1 He thought the flow of electric current was due to the contact between the two metals, whereas in fact it results from the chemical action of the electrolyte on the zinc plate. The Dawn of Amateur Radio in the U.K. and Greece: a personal view And where it came upon water some chemical action occurred, and the surface would be instantly covered with a powdery scum that sank slowly and made way for more. The War of the Worlds There can be no doubt that the chemical action, already mentioned, each time liberates fresh gold from some combination. The Voyage of the Beagle On closing the circuit of a primary battery an electric current is generated by reason of the chemical action which is set up between the electrolyte and the elements. Edison, His Life and Inventions Thus, that which is called simply conduction involves no chemical action, and apparently no displacement of the particles concerned. Experimental Researches in Electricity, Volume 1 The reverse current reverses the chemical action and re-establishes the original conditions, thus enabling the cell to repeat its electrical work. The Project Gutenberg Encyclopedia Volume 1 of 28 Dr. Draper* has observed a similar difference between the chemical action of light in New York and Virginia. History and Practice of the Art of Photography When moisture is added to baking powder, chemical action sets in, but it is not very rapid, as is apparent when a cake or a muffin mixture is allowed to stand before baking. Woman's Institute Library of Cookery Volume 1: Essentials of Cookery; Cereals; Bread; Hot Breads The storage battery also generates electric current through chemical action, but without involving the constant repriming with active materials to replace those consumed and exhausted as above mentioned.

Experimental Researches in Electricity, Volume 1 In the former, the anthracite and lime are ground and carefully mixed in the right proportions to suit the chemical actions involved. The Project Gutenberg Encyclopedia Volume 1 of 28 All attempts to lay bare this principle of vitality, or level the barriers that separate it from physical or chemical action, have utterly failed. Life: Its True Genesis When both moisture and heat are applied to baking powder, however, the chemical action that takes place is more rapid, and this accounts for its usefulness in baking hot breads and cake. Woman's Institute Library of Cookery Volume 1: Essentials of Cookery; Cereals; Bread; Hot Breads These chemical actions result in the generation of an electric current as in a primary battery. Edison, His Life and Inventions Wollaston endeavoured to refer such excitement to chemical action335; but if by chemical action ultimate union of the acting particles is intended, then there are plenty of cases which are opposed to such a view. Experimental Researches in Electricity, Volume 1 It declares that sulphate of lead is formed on both plates during discharge, the chemical action being reversed in charging. The Project Gutenberg Encyclopedia Volume 1 of 28 It is not inert matter organizing itself into life, nor any mode of physical or chemical action, nor any mere manifestation of motion or of heat, nor any other conceivable correlation of natural forces.

Scientific American, Volume 17, No. 26 December 28, 1867 A Weekly Journal of Practical Information, Art, Science, Mechanics, Chemistry, and Manufactures. It is exactly like the primary battery in the fundamental circumstance that its ability for generating electric current depends upon chemical action. Edison, His Life and Inventions The first is the case of volta-electric excitation, the other ordinary chemical affinity: but both are chemical actions and due to one force or principle. Experimental Researches in Electricity, Volume 1 Kelvin and Helmholtz have shown that the E.M.F. of a voltaic cell oan be calculated from the energy developed by the chemical action. The Project Gutenberg Encyclopedia Volume 1 of 28 The luminosity of the flame, however, ceases at a sharp line of demarkation, and evidently coincides with completion of the chemical action. Scientific American Supplement, No. 385, May 19, 1883 Neither does the living creature perform its functions by any other force than that which is developed by the chemical action within it, or the quasi combustion of its food. The Atlantic Monthly, Volume 02, No. 08, June 1858 One form of energy is convertible into another: heat, light, electricity, magnetism, chemical action, are so related that one can be made to produce either of the others. Outline of Universal History From the foregoing and many other experiments, it results that variation in the size of the electrodes causes no variation in the chemical action of a given quantity of electricity upon water. Experimental Researches in Electricity, Volume 1 For other strengths of acid, the energy will be less by the quantity of heat evolved by dilution of the acid, because the chemical action must take the H2SO4 from the diluted liquid. The Project Gutenberg Encyclopedia Volume 1 of 28 By its presence chemical action and decay are set up in many substances which would remain in a quiescent state so long as they continued dry. Scientific American Supplement, No. 384, May 12, 1883 Besides the chemical action affecting the hardness, it has another most important mechanical action, in consequence of the weight of each particle composing the precipitate produced by it.

Scientific American Supplement, No. 288, July 9, 1881 The weights N=14, Cl=35.5 occupy in the free state one volume, but in the combination, CNCl, two volumes; their specific gravity is, therefore, by chemical action reduced to one half. Scientific American Supplement, No. 286, June 25, 1881 When these are united and the silver chloride moistened, chemical action begins, and a weak but constant current is generated. Scientific American Supplement, No. 275, April 9, 1881 Quite so," answered Ah Ben, thoughtfully, "but, speaking frankly, this limitation of your powers to the chemical action of your body only shows the narrowness of your scientific training. The Ghost of Guir House As a matter of fact, the chemical action of the tobacco- smoke would define, upon a paper fitted into the mouth-piece of each cigarette, the photographic image of a dancing-girl. In Ghostly Japan To appreciate the chemical actions which may occur, it will be as well to examine analyses of sea-water and cement. The Sewerage of Sea Coast Towns The name is misleading, since even in this attempt electricity is in no sense "stored," but a chemical action producing a current takes place in the machine. Steam, Steel and Electricity By some curious chemical action, which they never understood, the liquid had been prevented from evaporating, nor was it frozen or petrified as was everything else on the moon. Lost on the Moon Or, in Quest of the Field of Diamonds “Some chemical action going on somewhere down there,” said he, half to divert his own attention from his thoughts. Darkness and Dawn Analogous chemical actions may take place in primitive and transition slates as well as in tertiary formations.

Man or Matter Or gross mechanical influences might pass, but no chemical action. Pragmatism "She could turn your hair a bright red like mine by mere chemical action of her ventilating system." Jane Allen, Junior You have an idea that all the wisdom in the world is locked up in the concrete; unless a thing has wheels, pistons, some sort of combustion, or a chemical action you are not interested. The Blind Spot Heat, pressure, chemical action change the crystalline structure, the texture, even form new minerals. Let's Collect Rocks and Shells In the last part of these studies a vista opened up of an inner differentiation of levity itself into warmth, light, chemical action and the formative activity of life. Man or Matter The introductory chapters deal with various sources of electrical energy, in friction, chemical action, heat and magnetism.

The Art of Living in Australia ; together with three hundred Australian cookery recipes and accessory kitchen information by Mrs. H. Wicken When we plunge the two metals, still in contact, either directly or through a wire, into water preferably acidulated, a chemical action is set up, the water is decomposed, and the zinc is consumed. The Story of Electricity I fear more than that the chemical action which would be set up in my soul by a false homage to a symbol behind which are massed twenty centuries of authority and veneration. A Portrait of the Artist as a Young Man On the contrary, the decay of rocks under the chemical action of water is favored by a warm, moist climate and abundant vegetation. The Elements of Geology These chemical actions, poetically denominates the "tooth of time," destroy all the works of man, and gradually reduce the hardest rocks to the condition of dust. Familiar Letters on Chemistry The other salts of lime, including its carbonate or calcite, although often met with, are invariably products of secondary chemical action.

An Introduction to Chemical Science They dissolve and decompose under the chemical action of water and the various corrosive substances which it contains, leaving their insoluble residues as residual clays and sands upon the surface. The Elements of Geology Precisely similar is the chemical action which takes place in the soil of our fields; and we accelerate and increase it by the mechanical operations of our agriculture. Familiar Letters on Chemistry Carbonate of lime, therefore, can rarely be precipitated at the bottom of the sea by chemical action alone, but must be produced by vital agency as in the case of coral reefs. The Student's Elements of Geology The "contact electricity" of the zinc and copper probably begins the process, and the chemical action keeps it up. The Story of Electricity In this respect it is a type of all chemical action. An Introduction to Chemical Science Karst, the name of a part of this country, is now used to designate any region or landscape thus sculptured by the chemical action of surface and ground water. The Elements of Geology As in a thousand other instances, chemical action here supplants mechanical forces. Familiar Letters on Chemistry But the matter which forms a chemical deposit has not been mechanically suspended in water, but in a state of solution until separated by chemical action. The Student's Elements of Geology Of these by far the most important are based on its property of developing light and heat as in the electric spark, chemical action as m the voltameter, and magnetism as in the electromagnet. The Story of Electricity However large the masses changed by chemical action, that action is always on the individual molecule, the atoms of which are separated. An Introduction to Chemical Science The theory with respect to these phenomena which appears most feasible is, that at these points certain chemical action has taken place, by which the deposition of the metals has been specially induced. Getting Gold: a practical treatise for prospectors, miners and students In that state in which they exist within the pores or upon the surface of solid bodies, their repulsion ceases, and their whole chemical action is exerted. Familiar Letters on Chemistry Its rays stimulate the growth of every living organism, and there is no doubt but they exert a chemical action upon living tissue with which we are as yet but imperfectly acquainted. The Royal Road to Health The generation of this current is accompanied by chemical action in the cell. The Story of Electricity In either case, a spontaneous heating follows, and chemical action is indicated by a change of color which reddens and darkens the leaf, and by the evolution of further pleasant "tea" odors. Tea Leaves Some chemical action on this preparation of steel caused a minute hole; from this point, branches like lichens, or the little ragged stars we sometimes see in thawing ice, radiated in all directions.

The Canterbury Tales, and Other Poems On the right hand the plates are connected by a wire outside the cell; the current starts, and the chemical action begins. The Story of Electricity You can't deny that there is such a thing as chemical action, chemical affinity, chemical combination—-the most irresistible of all natural forces. You Never Can Tell While this chemical action is of the utmost importance for organisms, the nutrition of which depends upon the action of chlorophyll, it becomes of less importance for organisms devoid of chlorophyll. Darwin and Modern Science He satisfied himself completely of the true identity of all the various forms of electricity, and of the convertibility of electricity and chemical action. A History of Science — Volume 3 When this was thrown into acid the coating was removed by chemical action, leaving the shining metal in the bottom of the vessel. A History of Science — Volume 2 Volta had found that two dissimilar metals in contact will produce a current by chemical action, and Seebeck showed that heat might take the place of chemical action.

Timaeus The quantity of electricity he concludes is proportional to the amount of chemical action. Faraday as a Discoverer Still, electricity generated by chemical action, even in a very perfect cell, was both feeble and expensive, and, withal, only applicable in a comparatively limited field. A History of Science — Volume 3 Even chemical action enters the sphere of explanation. The Story of Evolution It is stated that a certain blind operator could read the signals by the smell of the chemical action; and we can well believe it. The Story of Electricity Some, indeed, with Lyell, preferred to believe that the molten areas exist only as lakes in a solid crust, heated to melting, perhaps, by electrical or chemical action, as Davy suggested.
