Referring to the figure shown below, water contained in a piston–cylinder assembly, initially at 1.5 bar and a quality of 60%, is heated at constant pressure until the piston hits the stops. Heating then continues until the water is saturated vapor. The initial height, L1, is 0.05 m and the change in height, L2, is 0.03 m.




For the overall process of the water, evaluate the work and heat transfer, each in kJ/kg.

Kinetic and potential effects are negligible.
