हिन्दीA Carnot engine has an efficiency of \( 50\% \) when its source is at a temperature \( 327^\circ \, \text{C} \). The temperature of the sink is :
Correct answer · Option 4
\( 27^\circ \, \text{C} \)
Explanation
Source temperature \( T_1 = 327 + 273 = 600 \, \text{K} \). Efficiency \( \eta = 1 - \frac{T_2}{T_1} \Rightarrow 0.5 = 1 - \frac{T_2}{600} \Rightarrow T_2 = 300 \, \text{K} = 27^\circ \, \text{C} \).
