Stran 64 - Heat is a very brisk agitation of the insensible parts of the object, which produces in us that sensation, from whence we denominate the object hot ; so what in our sensation is heat, in the object is nothing but motion.
Stran 68 - On the Heat evolved by Metallic Conductors of Electricity, and in the cells of a battery during Electrolysis."— Phil.
Stran 96 - What its great purpose is, seems to be looming in the distance before us, the clouds which obscure our mental sight are daily thinning, and I cannot doubt that a glorious discovery in natural knowledge, and of the wisdom and power of God in the creation, is awaiting our age, and that we may not only hope to see it, but even be honoured to help in obtaining the victory over present ignorance and future knowledge.
Stran 93 - Clapeyron in a very able theoretical paper, of which there is a translation in the 3rd part of Taylor's Scientific Memoirs. This philosopher agrees with Mr. Carnot in referring the power to vis viva developed by the caloric contained by the vapour in its passage from the temperature of the boiler to that of the condenser. I conceive that this theory, however ingenious, is opposed to the...
Stran 93 - Believing that the power to destroy belongs to the Creator alone, I entirely coincide with Roget and Faraday in the opinion that any theory which, when carried out, demands the annihilation of force, is necessarily erroneous.
Stran 75 - That the quantity of heat produced by the friction of bodies, whether solid or liquid, is always proportional to the quantity of force extended.
Stran 82 - ... no change of temperature occurs when air is allowed to expand in such a manner as not to develop mechanical power.
Stran 64 - Heat is a motion, expansive, restrained, and acting in its strife upon the smaller particles of bodies. But the expansion is thus modified ; while it expands all ways, it has at the same time an inclination upwards. And the struggle in the particles is modified also ; it is not sluggish, but hurried and with violence.
Stran 178 - On the motion of the President, a hearty vote of thanks was passed to Mr.
Stran 93 - From them we may infer that the steam, while expanding in the cylinder, loses heat in quantity exactly proportional to the mechanical force which it communicates by means of the piston, and that on the condensation of the steam the heat thus converted into power is not given back.
