Encyclopaedia Britannica, 11th Edition, Volume 2, Slice 5 "Arculf" to "Armour, Philip" Several methods are in use, e.g. nitrogen may be removed by passing it repeatedly over red-hot magnesium; thus the nitrogen is absorbed and the argon left. The New Gresham Encyclopedia. Vol. 1 Part 2 Amiel to Atrauli He kept his eye on that something left, and presently discovered a new gas which we now know as argon. Astronomical Discovery Such shiftings are noted in the cases of tellurium and iodine; cobalt and nickel; argon and potassium. A Brief Account of Radio-activity In 1968, Dr. Patz began working with colleagues from the Johns Hopkins Applied Physics Laboratory to develop one of the early argon laser photocoagulators to treat diabetic retinopathy and other eye conditions. Dr. Arnall Patz, Who Saved Many From Blindness, Dies at 89 2010-03-16T02:31:00Z The facts detailed in the original memoir led to the conclusion that argon was an element or a mixture of elements, but the question between these alternatives was left open. Encyclopaedia Britannica, 11th Edition, Volume 2, Slice 5 "Arculf" to "Armour, Philip" Another method of preparing argon is by fractionation of liquid air. The New Gresham Encyclopedia. Vol. 1 Part 2 Amiel to Atrauli In air there is very little deposit from an Al cathode, but it is abundant in tubes filled with the monatomic gases, mercury vapour, argon or helium. Encyclopaedia Britannica, 11th Edition, Volume 6, Slice 8 "Conduction, Electric" In 1895, in connection with the discovery of argon in the atmosphere, a search was made to see if the latter element could be obtained from mineral sources. A Brief Account of Radio-activity But again, how chances it that different atoms attract one another in such varying degrees, so that, for example, fluorine unites with everything it touches, argon with nothing? A History of Science, Volume 5(of 5) Aspects Of Recent Science These gases agree with argon in respect of the ratio of the specific heats and in being non-oxidizable under the electric spark. Encyclopaedia Britannica, 11th Edition, Volume 2, Slice 5 "Arculf" to "Armour, Philip" It was impossible for human beings to exist without the addition of those elements existing in the air in minute quantities—neon, krypton, and argon. Astounding Stories of Super-Science, August 1930 Fill a gasometer with purified argon and we'll introduce a few of these crystals and explode them. Poisoned Air Radium then expels an alpha particle and becomes the gas, radium emanation, which is an analogue of argon and belongs to the zero group. A Brief Account of Radio-activity The discovery of argon came about in a rather singular way. A History of Science, Volume 5(of 5) Aspects Of Recent Science As originally defined, argon included small proportions of these gases, but it is now preferable to limit the name to the principal constituent and to regard the newer gases as “companions of argon.” Encyclopaedia Britannica, 11th Edition, Volume 2, Slice 5 "Arculf" to "Armour, Philip" In this respect it holds a position analogous to the argon of the atmosphere, and is capable of taking up the vibrations of those bodies to which it is related and which it invests. Second Sight A study of Natural and Induced Clairvoyance The level of the gas showed it to be of the original volume but the liquid under the argon was stained a light brown. Poisoned Air There would be traces of heavy gases—argon, neon, xenon, krypton, and volcanic carbon dioxide. The Planet Strappers Having discovered so interesting a substance as argon, Professor Ramsay and his assistants naturally devoted much time and attention to elucidating the peculiarities of the new substance. A History of Science, Volume 5(of 5) Aspects Of Recent Science Sir William Ramsay considers that probably the volume of all of them taken together does not exceed 1⁄400th part of that of the argon. Encyclopaedia Britannica, 11th Edition, Volume 2, Slice 5 "Arculf" to "Armour, Philip" So 'the truth' is not 'argon', it is a ferment. Expositions of Holy Scripture Ephesians; Epistles of St. Peter and St. John Both argon and helium have much lower boiling points than might be expected, judging from their densities. Scientific American Supplement, No. 1082, September 26, 1896 That there is little actual combustion is certain; that is, except for the forced combination of nitrogen, argon, xenon, and krypton with oxygen. The Vortex Blaster But consider a little further; the argon atom not only repels all advance on the part of oxygen and nitrogen, but it equally holds itself aloof from its own particular kindred atoms. A History of Science, Volume 5(of 5) Aspects Of Recent Science The residual argon, derived doubtless from the water used to manipulate the gases, was but a small fraction of what would have been obtained from a corresponding quantity of air. Encyclopaedia Britannica, 11th Edition, Volume 2, Slice 5 "Arculf" to "Armour, Philip" But the truth is no inert substance like the element which recent chemical discoveries have found, which is named 'argon,' the do-nothing: the truth is, as physiologists say, a ferment. Expositions of Holy Scripture Ephesians; Epistles of St. Peter and St. John The discovery of the chemical element argon came about through some exact measurements by Lord Rayleigh and Sir William Ramsay of the nitrogen and the oxygen in a glass flask. Human Traits and their Social Significance Out there, we were only cooled by radiation, but those streams are probably liquid nitrogen, oxygen, and argon, and there's a slight atmosphere of hydrogen, helium and neon cooled to about fifty degrees Absolute. Islands of Space The argon atom is just as closely in contact with the oxygen in the atmosphere as with the nitrogen; it simply repels each indiscriminately. A History of Science, Volume 5(of 5) Aspects Of Recent Science At this temperature the nitrogen combines with the magnesium, and thus the argon is concentrated. Encyclopaedia Britannica, 11th Edition, Volume 2, Slice 5 "Arculf" to "Armour, Philip" What property of magnesium was taken advantage of in the isolation of argon? An Elementary Study of Chemistry Briefly Arcot and Wade discussed the unusual atmosphere, finally deciding that the inert gas was argon. The Black Star Passes It is composed chiefly of oxygen and nitrogen,29 but it also contains a small per cent of other substances, such as water-vapor, carbon dioxide, and argon. Physiology and Hygiene for Secondary Schools The oxygen or nitrogen atom never rests until it has sought out a fellow, but the argon atom declines all fellowship. A History of Science, Volume 5(of 5) Aspects Of Recent Science The most remarkable physical property of argon relates to the constant known as the ratio of specific heats. Encyclopaedia Britannica, 11th Edition, Volume 2, Slice 5 "Arculf" to "Armour, Philip" This list includes the rare elements, argon, helium, neon, krypton, and xenon; also hydrogen, ammonia, hydrogen dioxide, and probably ozone. An Elementary Study of Chemistry Thus, Lord Rayleigh and Sir W. Ramsay found that nitrogen from the atmosphere was slightly heavier than nitrogen got from chemical sources; and, seeking the cause of this difference, discovered argon. Logic Deductive and Inductive In fact, the gas-filled tungsten lamp may be thought of as an ordinary lamp with its long filament made into a short helical coil and the bulb filled with nitrogen or argon gas. Artificial Light Its Influence upon Civilization A statement of the properties of argon was made by the discoverers to the Royal Society, given in Phil. A History of Science, Volume 5(of 5) Aspects Of Recent Science This is precisely the number found from the velocity of sound in argon as determined by Kundt’s method, and it leaves no room for any sensible energy of rotatory or vibrational motion. Encyclopaedia Britannica, 11th Edition, Volume 2, Slice 5 "Arculf" to "Armour, Philip" These elements, as well as helium, all proved to be similar to argon in that they are without chemical activity, apparently forming no compounds whatever. An Elementary Study of Chemistry We know how Sir William Ramsay and Dr. Travers first observed by means of the spectroscope the characteristics of the companions of argon in the least volatile part of the atmosphere. The New Physics and Its Evolution Above the photosphere comes a stratum of cooler vapours and gases, namely, hydrogen and helium, a very light element recently found on the earth, along with argon, in the rare mineral cleveite. A Trip to Venus In the first place the kinetic theory fixes the number of degrees of freedom of each gaseous molecule, which would be three for argon, for instance, and five for oxygen. A Librarian's Open Shelf This low refractivity is noteworthy as strongly antagonistic to the view at one time favoured by eminent chemists that argon was a condensed form of nitrogen represented by N3. Encyclopaedia Britannica, 11th Edition, Volume 2, Slice 5 "Arculf" to "Armour, Philip" When argon was discovered it was seen at once that there was no place in the table for an element of atomic weight approximately 40. An Elementary Study of Chemistry If it be a gaseous body, it must form part of the argon group, and, like its other members, be perfectly inert. The New Physics and Its Evolution Rayleigh, Lord, physicist, was senior wrangler at Cambridge; is professor of Natural Philosophy in the Royal Institution; author of "The Theory of Sound"; discovered, along with Professor Ramsay, "argon" in the atmosphere; b. The Nuttall Encyclopædia Being a Concise and Comprehensive Dictionary of General Knowledge There was no argon, no radium, no phagocytes—at least to my knowledge, and aluminium was a dear, infrequent metal. Tono Bungay At a pressure of 1 mm. the red glow of argon was readily obtained with a voltage of 2000, but not with much less. Encyclopaedia Britannica, 11th Edition, Volume 2, Slice 5 "Arculf" to "Armour, Philip" On this account it was given the name argon, signifying lazy or idle. An Elementary Study of Chemistry According to him, neither helium nor argon is absorbed by charcoal. The New Physics and Its Evolution Among the recent elements which have been discovered are argon, which enters into the composition of air, helium, and radium. Outline of Universal History "Oh! that, my dear," he answered, beaming over his spectacles with the good nature of superior wisdom, "is known as argon!" Toasts and Forms of Public Address for Those Who Wish to Say the Right Thing in the Right Way As soon as a spark-gap was introduced, or the condenser began to emit the humming sound peculiar to it, the beautiful blue glow so characteristic of argon immediately appeared. Encyclopaedia Britannica, 11th Edition, Volume 2, Slice 5 "Arculf" to "Armour, Philip" If the gas left after the removal of oxygen from a portion of air is passed over heated magnesium, the nitrogen is withdrawn, argon and the other rare elements being left. An Elementary Study of Chemistry The discovery of the radioactive mineral malacone, which gives off both helium and argon, goes to support this. The New Physics and Its Evolution Fifty miles above, the masses of nitrogen and oxygen and argon were too cold to change their rate of vibration. Ancient and Modern Physics But here I would rather attempt not to find a formula or a definition for humour, but to discover what it is, like argon, by eliminating other characteristics, until the evasive quality alone remains. At Large The behaviour of argon at low temperatures was investigated by K.S. Encyclopaedia Britannica, 11th Edition, Volume 2, Slice 5 "Arculf" to "Armour, Philip" It may thus be shown that of the 79 volumes of gas left after the removal of the oxygen from 100 volumes of air, approximately 78 are nitrogen and 0.93 argon. An Elementary Study of Chemistry The liquefaction of oxygen; the existence of radium, of helium, of polonium, of argon; the different powers of Roentgen and Cathode and Bequerel rays. The Jewel of Seven Stars Being less volatile than nitrogen, argon accumulates relatively as liquid air evaporates. Encyclopaedia Britannica, 11th Edition, Volume 2, Slice 5 "Arculf" to "Armour, Philip" This proved to be a new element, to which they gave the name argon. An Elementary Study of Chemistry Now that liquid air is available in many laboratories, it forms an advantageous starting-point in the preparation of argon.
