Consider a system consisting of 1.5 mol CO2(g), initially at 15C and 9.0 atm and confined to a cylinder of cross-section 100.0 cm2. The sample is allowed to expand adiabatically against an external pressure of 1.5 atm until the piston has moved outwards through 15 cm. Assume that carbon dioxide may be considered a perfect gas with Cv,m=28.8 J K-1 mol-1. Calculate
