A piston-cylinder assembly contains 0.7 lb of propane. The propane expands from an initial state where p₁ = 60 lbf/in.2 and T₁ = 50°F to a final state where p2 = 10 lbf/in. During the process, the pressure and specific volume are related by pv² = constant. Determine the energy transfer by work, in Btu.
