Question 5 POST_UTME_EKSU • 2019 • PHYSICS • objective

A heat engine operates between two temperatures $T_1 = 300 , \text{K}$ and $T_2 = 200 , \text{K}$. If the engine produces $W = 100 , \text{J}$ of work, determine the efficiency of the engine.

Correct Answer A. $ eta = \frac{W}{Q_1} $

B. $ eta = \frac{W}{Q_2} $

C. $ eta = \frac{W}{T_1 - T_2} $

D. $ eta = \frac{W}{T_1 + T_2} $

Correct Answer

Correct Option:

$ eta = \frac{W}{Q_1} $
