Question 35 POST_UTME_CHRISTOPHER_UNIVERSITY • 2017 • PHYSICS • objective

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

Answer Options

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