Page 173 - Since all matter may be made to fill a smaller space by cooling, ! it is evident that the particles of matter must have space between them ; and, since every body can communicate the power of expansion to a body of a lower...
Page 21 - I often say that if you can measure that of which you speak, and can express it by a number, you know something of your subject ; but if you cannot measure it, your knowledge is meagre and unsatisfactory.
Page 174 - ... 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 or undulating motion, or a motion of the particles round their axes, or a motion of particles round each other.
Page 174 - ... the particles move round their own axes, and separate from each other, penetrating in right lines through space. Temperature may be conceived to depend upon the velocity 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...
Page 174 - It seems possible to account for all the phenomena of heat, if it be 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 fluids and elastic fluids, besides the vibratory motion, which must be conceived greatest in the last, the particles have a motion round their own axes with different velocity, the particles of elastic fluids moving with the greatest quickness,...
