A)converts heat input to an equivalent amount of work
B)converts work to an equivalent amount of heat
C)takes heat in, does work, and loses energy as heat

E)uses positive work done on the system to transfer heat from a high temperature reservoir to a low temperature reservoir

Question

Quizplus · Accepted Answer

A heat engine takes in heat at a high temperature, does work, and then releases heat at a lower temperature. It does not convert heat to work or work to heat, but instead converts some of the input heat into useful work while losing some as waste heat. It also does not transfer heat from a low temperature reservoir to a high temperature reservoir, but instead operates in the opposite direction.
