3.6(a) Consider a system consisting of 2.0 mol CO2(g), initially at 25°C and
10 atm and confined to a cylinder of cross-section 10.0 cm2
. It is allowed to
expand adiabatically against an external pressure of 1.0 atm until the piston
has moved outwards through 20 cm. Assume that carbon dioxide may be
considered a perfect gas with CV,m = 28.8 J K−1

and calculate (a) q, (b) w,
(c) ΔU, (d) ΔT, (e) ΔS.
