Ammonia in a piston-cylinder assembly undergoes two processes in series. Initially, the ammonia is saturated vapour at P₁=1000 kPa. Process 1-2 involves cooling until the piston meets the stops where the position is locked in place at which time quality is x2=75%. The second process from state 2 to state 3, involves heating (at constant volume) until x3=100%. If the mass is 0.45 kg determine: The work for process 2-3 (in kJ).

Air as an ideal gas is contained in a piston/cylinder system constrained by a non-linear spring. Initially the gas in the cylinder is at 100 kPa, which is balanced by the atmospheric pressure outside of the cylinder (the weight of the piston is negligible). The force on the spring at the start is zero. The spring force is F=kx². k=600. kNt/m². The cross-sectional area of the piston is 1 m², the initial volume is 1 m³, and the initial temperature is 300 K. Heat is added until the volume of the gas has expanded to 1.5 m³.
