One kg of ammonia in a piston-cylinder assembly, initially saturated liquid at 5 bar, is boiled at constant pressure to saturated vapor. Kinetic and potential energy changes are negligible. a) evaluate the heat transfer [Btu] for this process;b) calculate the entropy production [kJ/K] for this process assuming that the heat transfer occurs with a heat reservoir at 277.28 K. c) Explain on a thermodynamic basis why this process reversible, irreversible or impossible; d) show the states and process on P-v and T-s diagrams.
