Consider a piston-cylinder device that contains 0.5m^3 of saturated water vapor at 0.2MPa and where the piston initially rests on a set of stops. The mass of the piston is such that it takes 0.3MPa of pressure to move it. Heat is transferred to the steam until the system volume doubles. Determine:
a.) The final temperature
b.) The work done
c.) The total heat transfer
