A Carnot cycle operates with an efficiency 0.60 between a low temperature heat bath at 20.0°C and a high temperature heat bath. What is the temperature of the high temperature heat bath?

Question

Quizplus · Accepted Answer

The efficiency of a Carnot engine is given by 1 - (T_cold/T_hot), where temperatures are in Kelvin. Converting 20°C to Kelvin gives 293K. Setting up the equation 0.60 = 1 - (293/T_hot) and solving for T_hot gives approximately 733K, which is 460°C.
