The efficiency of a Carnot engine depends upon (a) the temperature of the source only (b) the temperature of the sink only (c) the temperatures of the source and sink (d) the volume of the cylinder of the engine

Answer: (c). η = 1 - (T₂)/(T₁) depends only on the source temperature T₁ and sink temperature T₂. So the answer is (c).

The efficiency of a Carnot engine depends upon

Show answer and solution

Answer: (c)

$\eta = 1 - \frac{T_2}{T_1}$ depends only on the source temperature $T_1$ and sink temperature $T_2$ .
So the answer is (c).
