Question 38 POST_UTME_MOUNTAIN_TOP_UNIVERSITY • 2020 • PHYSICS • objective

A heat engine operates between two temperatures $T_1$ and $T_2$. If the efficiency of the engine is $\eta = 1 - \frac{T_2}{T_1}$, find the temperature of the hot reservoir in terms of the efficiency and the temperature of the cold reservoir.

Answer Options

Correct Answer A. \frac{T_2}{T_1} = 1 - \eta
B. \frac{T_2}{T_1} = \eta - 1
C. \frac{T_2}{T_1} = \frac{\eta}{1 - \eta}
D. \frac{T_2}{T_1} = \frac{1 - \eta}{\eta}
Correct Answer
A
Correct Option:
\frac{T_2}{T_1} = 1 - \eta
