A Carnot engine has an efficiency of $50\%$ when its source is at a temperature $327°$ C. The temperature of the sink is :
Answer: (A) $27°$ C
Concept. Carnot efficiency $\eta = 1 - \dfrac{T_2}{T_1}$ with absolute temperatures.
Step 1. Source. $T_1 = 600$ K.
Step 2. Sink. $0.5 = 1 - \dfrac{T_2}{600} \Rightarrow T_2 = 300$ K $= 27°$C.
Answer. $27°$C (Option A).
