A solar hot water heater raises the temperature of 200 liters of water from 27 to 47 degrees C. Suppose a heat engine with 40 percent of the efficiency of a Carnot engine had absorbed the same amount of heat at 600K and rejected waste heat at 300K. If the output of that engine were converted into electric power with an efficiency of 90 percent and that electric power were dissipated in a resistance heater, how much water would have been heated through the same temperature interval, that is, 27 to 47 degrees celsius?
