All of the above.

Vedclass · Answer

(D) heat engine is a device that converts heat energy into mechanical work through a cyclic process.$1$. It absorbs heat from a high-temperature source $(T_H)$.$2$. It performs some amount of work $(W)$.$3$. It rejects the remaining heat to a low-temperature sink $(T_L)$.$4$. Since it operates in a cyclic process, the change in internal energy $(\Delta U)$ of the system over one complete cycle is zero $(\Delta U = 0)$.Therefore, all the mentioned features are characteristic of a heat engine.

What is the common feature of a heat engine based on a cyclic process?
