The Smart Way to Play God with Earth's Limited Land 2012-01-20T22:15:00.427Z But there is a fundamental problem: photosynthesis, the process by which plants convert sunlight into stored chemical energy, is highly inefficient. Scientists Tweak Photosynthesis in Pursuit of a Better Biofuel 2012-01-13T13:15:00.313Z First we have transformation of chemical energy, without which continued life is impossible: in many cases—e.g. the processes connected with oxygen respiration—these result in the development of heat. Disease in Plants 2012-03-01T03:00:22Z “These communities are so special because they rely on chemical energy rather than light energy from the sun,” Dr. Rogers said.

The Mechanism of Life To which we must add a large allowance for waste, or thermal mechanical and chemical energy ineffectually dissipated in and above the vents. The Eruption of Vesuvius in 1872 From a given quantity of chemical energy represented, let us say, by a certain weight of coal, we can get a certain fixed amount of heat and no more. Coal and What We Get from It These motions are maintained at the expense of chemical energy liberated in the oxidative breakdown of carbohydrate, fat, and protein. Food in War Time Until now we have produced steam through the chemical energy of burning mineral coal. Woman under socialism The step which we do not as yet fully understand is the physical phenomenon which intervenes between the disengagement of chemical energy and the occurrence of muscular contraction. The Mechanism of Life Made of very complex molecules holding a considerable amount of chemical energy in the potential state, they are like explosives which only need a spark to set free the energy stored within them. Creative Evolution The chemical energy represented by the satisfaction of the chemical affinities of a grain of water and four grains of zinc can evolve electricity equal in quantity to that of a powerful thunderstorm. The World's Greatest Books — Volume 15 — Science One of these forms of energy is the chemical energy, with its tendency to combinations and exchanges. Manhood of Humanity. Mechanical and chemical energy, sound and heat, light and electricity, are mutually convertible; they seem to be but different modes of one and the same fundamental force or energy. The Approach to Philosophy So again with chemical energy, the molecular motion of combustion may be transformed into the radiant energy of the ethereal waves. The Mechanism of Life In consequence, however, of their chemical energy these ultra-violet rays are of the utmost importance to the organic world. Fragments of science, V. 1-2 The old-fashioned, oil- or coal-burning power plants converted chemical energy into heat energy, converted that into kinetic energy, and that, in turn was converted into electrical energy. Damned If You Don't It is obvious that no amount of chemical energy in food can account for such an energy as the time-binding energy. Manhood of Humanity. Since the energy possessed by coal only becomes available when the coal is made to undergo a chemical change, it is sometimes called chemical energy. An Elementary Study of Chemistry Muscles, then, are merely transformers which change chemical energy into mechanical work, the diminution of stored-up energy in a muscle being expressed by the sensation of fatigue. The Mechanism of Life A layer one-eighth of an inch in thickness, which scarcely perceptibly affected the luminous intensity, absorbed the entire chemical energy of the concentrated beam of the electric light. Fragments of science, V. 1-2 The chemical energy brought into existence by firing the explosive manifesting itself as mechanical energy, sufficient to impart violent motion to tons of water. The Outline of Science, Vol. 1 (of 4) A Plain Story Simply Told The plants have a very definite and well known function—the transformation of solar energy into organic chemical energy. Manhood of Humanity. There must be an all-potent energy transformation before we can get chemical energy out of physical energy, and then biotic energy out of chemical energy. The Breath of Life It may be asked by what path does the chemical energy of the living organism pass into the mechanical energy of motion. The Mechanism of Life Radiant energy or light is absorbed and converted into chemical energy. Artificial Light Its Influence upon Civilization Energy exists in many forms: energy of motion, heat, gravitational energy, chemical energy, radiation, and so on. Recent Developments in European Thought But the chemical energy of the sun's rays is not the sole cause of the fading of colors. Scientific American Supplement, No. 810, July 11, 1891 In like manner, a man is a machine for converting chemical energy derived from the food he eats into motion, and the like. The Breath of Life A catalyzer is the friction of the match which sets free the chemical energy of the powder magazine. The Mechanism of Life They convert the radiant energy into chemical energy and use this energy in decomposing the carbon dioxide. Artificial Light Its Influence upon Civilization In the year 1840 he was already speculating on the transformation of chemical energy into heat. Scientific American Supplement, No. 363, December 16, 1882 Once in the human body, these tense vehicles, the atoms, are discharged in the body's protoplasm, the radiance furnishing new chemical energy, new electrical currents. Autobiography of a Yogi In the living body the chemical energy of food is directly transformed into work, without first being converted into heat. The Breath of Life Soon, it is no longer bread or beef; it is flesh on your arm; its chemical energy is imparted to you, and it becomes your strength. Hygienic Physiology : with Special Reference to the Use of Alcoholic Drinks and Narcotics In a rough way we might thus say that the chemical energy of the food indirectly produces the motion of these little nerve-molecules. The Unseen World and Other Essays It simply produces some other motion of nerve-molecules, and this in turn produces motion of contraction or expansion in some muscle, or becomes transformed into the chemical energy of some secreting gland.
