(3). A sample of 1.00 mol ideal gas molecules with Cp, m = 7/2 R is initially at p = 1.00 bar and V = 22.44 L and then put thought the following cycle in reversible processes: (a) constant-pressure expansion to twice its initial volume, (b) constant-volume cooling to its initial temperature, (c) isothermal-compression back to 1.00 bar. Calculate q, w, AU, AH, AS for each process and for the whole cycle. (20 pts)

For a certain perfect gas, CV,m = 2.5R at all temperatures. Calculate q, w, ?U, ?H, and ?S when 2.00 mol of this gas undergoes each of the following processes: (a) a reversible isobaric expansion (1.00 atm, 20.0 L) to (1.00 atm, 40.0 L). (b) A reversible isothermal compression from (0.500 atm, 40.0 L) to (1.00 atm, 20.0 L).
