Question 4 POST_UTME_CHRISTOPHER_UNIVERSITY • 2019 • PHYSICS • objective

A heat engine operates between two reservoirs at temperatures $T_1$ and $T_2$. If the engine absorbs heat $Q_1$ from the high-temperature reservoir and rejects heat $Q_2$ to the low-temperature reservoir, find the efficiency of the engine.

Answer Options

Correct Answer A. \( \eta = \frac{Q_1 - Q_2}{Q_1} \)
B. \( \eta = \frac{Q_1}{Q_1 - Q_2} \)
C. \( \eta = \frac{Q_2}{Q_1 - Q_2} \)
D. \( \eta = \frac{Q_1 + Q_2}{Q_1} \)
Correct Answer
A
Correct Option:
\( \eta = \frac{Q_1 - Q_2}{Q_1} \)
