A reversible heat engine operates between two reservoirs: one at Th = 395.0°C and another at Te = 150°C. It goes through a cycle consisting of an adiabatic compression during which it ab- sorbs 125.0J of heat energy, followed by an isothermal expansion at Th, followed by an adiabatic expansion, followed by an isothermal compression at Te. The output of the engine is used to run a reversible refrigerator operating between the same two reservoirs, that has a cycle consisting of an adiabatic expansion, followed by an isothermal expansion at Te, followed by an adiabatic com- pression, followed by an isothermal compression at Th. The output of the engine is used to run the refrigerator. c) How much heat is released by the refrigerator to the hot reservoir?
