A '''heat engine''' typically uses energy provided in the form of heat to do work and then exhausts the heat which cannot be used to do work. They operate in a cyclic manner and are usually illustrated by a PV diagram.

A [[heat pump]] can be considered to be a "heat engine in reverse", in which energy is ''applied'' to transfer heat into or out of an area as desired. | |||
