A piston-cylinder assembly contains 2 lb of water, initially at 100 lbf/in.² and 350°F. The water undergoes two processes in series: a constant-pressure process followed by a constant volume process. At the end of the constant-volume process, the temperature is 300°F and the water is a two-phase liquid-vapor mixture with a quality of 50%. Neglect kinetic and potential energy effects. Determine the work and heat transfer for each process, all in Btu.
