Two moles of an ideal monatomic gas initially at 350 K is expanded from an initial pressure of 10 atm to a final pressure of 1 atm. Calculate ΔU, q, w, ΔH, and the final temperature T2 for this expansion carried out according to each of the following paths. The molar heat capacity at constant volume for a monatomic gas is C¯V,m = (3/2)R. (a) An isothermal, reversible expansion. (b) An expansion against a constant external pressure of 1 atm in a thermally isolated (adiabatic) system. (c) An expansion against zero external pressure (i.e. against a vacuum) in an adiabatic system.
