Page 1 - ... lower temperature, that is, can give an expansive motion to its particles, it is a probable inference that its own particles are possessed of motion ; but, as there is no change in the position of its parts as long...
Page 14 - ... the means frequently employed by gardeners, to protect tender plants from cold, as it appeared to me impossible, that a thin mat, or any such flimsy substance, could prevent them from attaining the temperature of the atmosphere, by which alone I thought them liable to be injured. But, when I had learned, that bodies on the surface of the earth become, during a still and serene night, colder than the atmosphere, by radiating their heat to the heavens, I perceived immediately a just reason for...
Page 1 - Temperature may be conceived to depend upon the velocities of the vibrations; increase of capacity on the motion being performed in greater space ; and the diminution of temperature during the conversion of solids into fluids or gases, may be explained on the idea of the loss of vibratory motion, in consequence of the revolution of particles round their axes, at the moment when the body becomes fluid or aeriform, or from the loss of rapidity of vibration in consequence of the motion of the particles...
Page 1 - The immediate cause of the phenomena of heat, then, is motion, and the laws of its communication are precisely the same as the laws of the communication of motion.
Page 11 - Monge has discovered that the pyroligneous acid obtained from the distillation of wood has the property of preventing the decomposition and putrefaction of animal substances. It is sufficient to plunge meat for a few moments into this acid, even slightly empyreumatic, to preserve it as long as you please.
Page 16 - But the casket contains other combinations, which, if wasted, could not be resupplied ; at least by any process which the great Master from whom I received them placed within reach of my knowledge. In this they resemble the diamond; when the chemist has found that the diamond affords no other substance by its combustion than pure carbonic acid gas, and that the only chemical difference...
Page 29 - The crude pyrolignous acid is rectified by a second distillation in a copper still, in the body of which about 20 gallons of viscid tarry matter are left from every 100. It has now become a transparent brown vinegar, having a considerable empyrcumatic smell, and a sp.
Page 1 - ... temperature, that is, can give an expansive motion to its particles, it is a probable inference that its own particles are possessed of motion; but as there is no change in the position of its parts as long as its temperature is uniform, the motion, if it exist, must be a vibratory orundulatory motion, or a motion of the particles round their axes, or a motion of particles round each other.
Page 1 - ... supposed that in solids the particles are in a constant state of vibratory motion, the particles of the hottest bodies moving with the greatest velocity, and through the greatest space; that in...
Page 8 - The form of the flame is conical, because the greatest heat is in the centre of the explosive mixture. • In looking steadfastly at flame...
