Q.4 Consider a system consisting of 1.5 mol CO2(g), initially at 15°C 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 Cy,m = 28.8 J K-1 mol, and calculate : q, w, AU, AT and AS.
