A piston cylinder device initially contains 1.2kg of saturated liquid water at 220oC. Now, heat is transferred to the water until the volume quadruples and the cylinder contains saturated vapor only. Determine (a) the final volume of the tank, (b) the final temperature (c) the final pressure, and (d) the change in internal energy of the tank. To check your work, enter the final pressure in kPa in the box below.  Also, sketch this process on a T-v diagram.
