1. A piston-cylinder assembly contains 0.1 lb of propane. The propane expands from an initial state where p1 5 60 lbf/in.2 and T1 5 30°F to a final state where p2 5 10 lbf/in.2 During the process, the pressure and specific volume are related by py2 5constant. Determine the energy transfer by work, in Btu.
