The temperature of the hot reservoir is raised by 35°C in order to increase the efficiency of the engine. (a) What is the efficiency after the increase in temperature? % (b) Instead of raising the temperature of the hot reservoir, if the temperature of the cold reservoir is decreased by 35°C, what would be the efficiency of the engine? % Additional Materials Reading 4.
