A heat engine operates between a high-temperature reservoir


A heat engine operates between a high-temperature reservoir at670K and a low-temperature reservoir at 320 K. In one cycle, the engine absorbs4500J of heat from the high-temperature reservoir and does 2200 J ofwork. What is the magnitude of the net change in entropy as a result of this cycle?
