A reversibly operating heat engine operates between two reservoirs with temperatures between 600 ℃ and 40 ℃, and the heat energy supplied to the heat engine from the 600 ℃ reservoir is 2000 kJ. This heat engine operates a refrigerator that operates reversibly between two reservoirs with temperatures between 40°C and -20°C. Since the net work output of the whole system is 360 kJ; (a) Calculate the net amount of heat transferred to the refrigerator and the reservoir at 40℃. (The reservoir at 40℃ is common for both refrigerator and heat machine.) (b) What would happen if the heat engine and refrigerator were working at 40% efficiency rather than reversibly? Recalculate part (a) for this case.
