Question

A heat engine is operating in between 500 K and 400 K. If the engine absorbs 100 J heat per cycle, then which of the following is impossible amount of heat rejected by the engine per cycle?

Accepted Answer

In reversible cycle, heat rejected is minimum. For reversible cycle,$\left| q_{rev} ight| = \frac{T_{C}}{T_{H}} 	imes q_{abs} = \frac{400}{500} 	imes 100 = 80	ext{ J}$
