Heat engine

Question

For which combination of working temperatures of source and sink, the efficiency of Carnot's heat engine is maximum?

Moderate

A

600 K, 400 K
B

400 K, 200 K
C

500 K, 300 K
D

300 K, 100 K

Solution

The efficiency of Carnot's heat engine, $η = \frac{T_{1} - T_{2}}{T_{1}}$
For given combinatlons $η_{1} = \frac{1}{3}, η_{2} = \frac{1}{2}, η_{3} = \frac{2}{5}, η_{4} = \frac{2}{3}$
So, it is maximum for $T_{1} = 300 K and T_{2} = 100 K$
