The ideal efficiency for a heat engine operating between the temperatures of 227°C and 27°C is

Question

Quizplus · Accepted Answer

The ideal efficiency of a heat engine is calculated using the Carnot efficiency formula: $ \eta = 1 - \frac{T_c}{T_h} $, where $ T_c $ and $ T_h $ are the absolute temperatures (in Kelvin) of the cold and hot reservoirs, respectively. Converting the given temperatures to Kelvin: $ T_h = 227°C + 273 = 500K $ and $ T_c = 27°C + 273 = 300K $. Thus, $ \eta = 1 - \frac{300}{500} = 0.4 $ or 40%.
