An insulated piston-cylinder device with a vertical axis, Ask an Expert

Academics

An insulated piston-cylinder device with a vertical axis 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?
