Physics

A heat engine operates between two reservoirs at T2 =600 K and T1 = 350 K. It takes in 1 000 J of energy fromthe higher-temperature reservoir and performs 250 J of work. Find(a) the entropy change of the Universe delta SUfor this process and (b) the work W that could have beendone by an ideal Carnot engine operating between these tworeservoirs. (c) Show that the difference between the amounts ofwork done in parts (a) and (b) is T1 deltaSU .
