A piston/cylinder contains 0.5 kg of water at 200 kPa, 300◦C, and it now cools to 150◦C in an isobaric process. The heat goes into a heat engine that rejects heat to the ambient at 25◦C (shown in Fig. P6.46), and the whole process is assumed to be reversible. Find the heat transfer out of the water and the work given out by the heat engine.
