Heat-A Matter of Motion
During the 1840s, many scientists recognized that heat is not a substance but a form of energy that can be converted into other forms. James Prescott Joule and Rudolf Clausius went a step further. Heat can produce mechanical energy, and mechanical energy can produce heat; therefore, they reasoned, the “heat energy” of a substance is simply the kinetic energy of its atoms and molecules. This idea, which forms the basis of the kinetic-molecular theory of heat, is largely correct.
