Water in the pictured piston cylinder assembly has an initial quality of 10%. The piston cylinder is 20 cm in width and the piston is initially 40 cm high. Heat is added until the temperature of the steam reaches 500°C. While heat is being added the piston rises 50 cm and hits a set of stops.

Find a) the initial pressure, b) mass of the system, c) temperature when the piston hits the stops, d) final pressure of the steam, e) the net heat transfer, and f) net work done.
