What is the maximum possible efficiency of a steam engine operating between a high and low temperature of 550°C and 180°C?

Question

Quizplus · Accepted Answer

The maximum possible efficiency of a steam engine is given by the Carnot efficiency, which is:η = 1 - (T_L / T_H)where T_L is the low temperature and T_H is the high temperature.In this case, T_L = 180°C + 273 = 453 K and T_H = 550°C + 273 = 823 K.Therefore, the maximum possible efficiency is:η = 1 - (453 / 823) = 0.45 = 45%So the correct answer is A.
