👉 In thermodynamics, a calorist is an entity that converts heat energy from one medium to another. They are responsible for transferring heat energy between two objects through a specific path or medium, which may be either solid, liquid, gas, or even vacuum. The process of converting heat energy from one medium to another involves the transfer of thermal energy, typically in the form of light or sound waves. In thermodynamics, calorists play a crucial role in maintaining stable temperatures and chemical reactions within systems.
