A steam engine with a boiler temperature of 227^oC and an exhaust temperature of 27^oC has a maximum efficiency of approximately

Question

Quizplus · Accepted Answer

The maximum efficiency of a heat engine is given by the Carnot efficiency formula: 1 - (T_cold/T_hot), where temperatures are in Kelvin. Converting the given temperatures to Kelvin (227°C = 500K, 27°C = 300K), the efficiency is 1 - (300/500) = 0.4 or 40%.
