A piston-cylinder assembly contains 2lb of water, initially at 100lbf/in.2 and 450∘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 40%. Neglect kinetic and potential energy effects. Determine the work and heat transfer for each process, all in Btu.
