A Carnot engine produces 8 kW by transferring 20 kJ/s to a 20°C reservoir. The temperature TH is nearest:
A) 410°C
B) 342°C
C) 278°C
D) 137°C
The heat transfer from the high-temperature reservoir is QH =QL +W = 20 + 8 = 28 kJ/s. The efficiency of the engine is thus 
The Carnot efficiency yields 
Obviously the temperatures must be absolute.
