Solution

Q.
A Carnot engine has an efficiency of 50% when its source is at a temperature 327°C. The temperature of the sink is [2023]

1 100°C

2 200°C

3 27°C

4 15°C

Ans.
(3)

Efficiency of Carnot engine is

$η = 1 - \frac{T_{2}}{T_{1}}$

Where, $T_{1}$ is the temperature of the source and $T_{2}$ is the temperature of the sink.

Given that, $η = 50 %,$ $T_{1} = 327 ° C = 600$ $K$

$T_{2} = ?$

$∴$ $\frac{50}{100} = 1 - \frac{T_{2}}{600} \Rightarrow T_{2} = 300 K$

or $T_{2} = 300 - 273 = 27 ° C$
