An insulated piston-cylinder device with a vertical exis initially contains 10 liters of saturated H2O vapor at 130degC. The piston is initially held in place by a locking pin, while the piston mass is 30 kg, its area is .003m^2, and the ambient pressure is 100 kPa. The pin is then removed and the H2O expands rapidly and adiabatically. What is the final state of the H2O?
