 The dynamical theory, or, as it is sometimes called, the mechanical theory of heat, discards the idea of materiality as applied to heat. The supporters of this theory do not believe heat to be matter, but an accident or condition of matter ; namely, a...

...as we have said, attributed to the influence of heat, is heat itself. "Heat," says Tyndall, " is not matter, but an accident or condition of matter, namely, a motion of its ultimate particles." " The condition of heat," says Eankine, "is a condition of energy — ie, of capacity to effect changes."... | |
