Question

Consider a system consisting of 2.0 mol Carbon dioxide gas, inititially at 25 deg and 10 atm and confined to a cylinder of cross section 10.0square centimeters. lt is allowed to expand adiabatically against an external pressure of 1.0atm until the piston has moved outwards through 20cm. Assume that Carbon dioxidemay be considered a perfect gas with Cv,m 28.8 JK/mol calculate q, w, delta U, delta T and delta S.
