1. a) A heat engine with an efficiency of 25% does 600 J of work in each cycle. How much heat must be supplied from the high-temperature source in each cycle? b) A heat engine with an efficiency of 40% takes in 800 J of heat from the high-temperature reservoir in each cycle. How much work does the engine do in each cycle? How much heat is released to the low-temperature reservoir?
