caloric theory of heat The view, formalized by Antoine Lavoisier toward the end of the 18th century, that heat consists of particles of a weightless, invisible fluid, caloric, which resides between the atoms of material substances. The theory fell from favor as physicists began to appreciate the equivalence of work and heat.
