Water contained in a piston-cylinder assembly as shown in the Figure below, initially at 1.5 ??? and a quality of 20%, is heated at a constant pressure until the piston hits the stops. Heating then continues until the water is saturated vapor. Show the processes of the water in series on a sketch of the ?-? diagram. For the overall process of the water, evaluate the work and heat transfer, each in ??⁄??. Kinetic and potential effects are negligible. (please show your work)

Refrigerant 134a, initially (state 1) a saturated liquid at -80C, is contained in a piston-cylinder assembly. The water undergoes a process to the corresponding saturated vapor (state 2), during which the piston moves freely in the cylinder. The change of state is brought about by heating the water as it undergoes an internally reversible process at constant pressure and temperature. If the mass of the refrigerant is 0.1 kg, determine (a) heat transfer using first law of thermodynamics in kJ...

A piston–cylinder assembly contains 2 lb of water, initially at 100 lbf/in.2 and 600°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.
