A Carnot engine operates between temperatures of 665 and 315 K. To improve the efficiency of the engine, it is decided either to raise the temperature of the hot reservoir by 39 K or to lower the temperature of the cold reservoir by 39 K. Which change gives the greatest improvement? raise the temperature of the hot reservoir lower the temperature of the cold reservoir Correct: Your answer is correct. Justify your answer by calculating the efficiency in each case. raise TH Incorrect: Your answer is incorrect. lower TC
