57. mmh A Carnot engine operates between temperatures of 650 and 350 K. To improve the efficiency of the engine, it is decided either to raise the temperature of the hot reservoir by 40 K or to lower the temper- ature of the cold reservoir by 40 K. Which change gives the greater im- provement? Justify your answer by calculating the efficiency in each case.
