Heat-Mechanicalism

Heat-Mechanicalism is the idea that states that heat is derived from the vibration of atoms. Unlike caloric theory, it states that heat transfer is the exchange of vibrational energy from the particles of the hotter object to the particles of the cooler object. Gases would have very fast-moving particles, which would speed up at higher temperatures. In other words, heat is the kinetic/vibrational energy of particles.
