A piston held by a pain in an insulated cylinder, contains 2 kg water at 100 degree C, quality 95%. The piston has a mass of 102 kg, with cross-sectional area of 100 cm^2, and the ambient pressure is 100 kPa. The pin is released, which allows the piston to move. Determine the final state of the water assuming the process to be adiabatic.(1Q2=0)
