An insulated vertical piston–cylinder device initially
Chapter 5, Problem 134P(choose chapter or problem)
An insulated vertical piston-cylinder device initially contains \(0.8 \mathrm{~m}^{3}\) of refrigerant-\(134a\) at \(1.4 \mathrm{MPa}\) and \(120^{\circ} \mathrm{C}\). A linear spring at this point applies full force to the piston. A valve connected to the cylinder is now opened, and refrigerant is allowed to escape. The spring unwinds as the piston moves down, and the pressure and volume drop to \(0.7 \mathrm{MPa}\) and \(0.5 \mathrm{~m}^{3}\) at the end of the process. Determine (a) the amount of refrigerant that has escaped and (b) the final temperature of the refrigerant.
