A frictionless piston cylinder device with a set of stops contains .5m^3 of saturated H2O vapor at 200 kPa. At this state, the piston rests on the stops and the piston mass is such that a pressure of 300 kPa is required to move it. Heat is transfered to the H2O until its volume doubles.
a) determine the final temp
b) calculate the sign and magnitude of work done and heat transfer in this process.
