Cierra Rogers · Answer 1

d. Take heat of entry, perform work and lose energy as heat

Explanation:

A thermal machine is a machine which take heat as input and perform some work then reject some heat.

A heat engine is a thermal machine which take heat from high temperature reservoir and rejecting the heat to the low temperature reservoir while performing some positive work. High temperature reservoir is known as source and the low temperature reservoir is known as sink.

So the option d is correct.

d. Take heat of entry, perform work and lose energy as heat
