**Question 8:**An ideal gas from an initial state of 21°C and 1 atm is compressed adiabatically to 65.6°C, followed by isobaric cooling to 21°C and finally expanded isothermally to its original state. Calculate the heat (Q), work done (W), change in enthalpy (ΔH), and change in internal energy (ΔU) for each step and for the entire process. If the same changes are brought about by an irreversible process, which quantity will differ and by how much? Take efficiency to be 75%. Given: Cv = 3/2R.

As Cv=32R CP - CV =RCP = 52R γ = CPCV= 52 R32 R =1.66

Part A: 10 moles of ideal gas initially at 10 atm and 250 K is expanded isothermally and reversibly to a final pressure of 2 atm. Calculate W; U; and Q in Joules. Part B: The same gas in part A, starting in the same initial state, is expanded isothermally against a constant external pressure of 2 atm, to a final pressure of 2 atm. Calculate W; U; and Q in Joules for this irreversible process. Part C: The same gas in part B, starting in the same initial state, is expanded isothermally to a nal pressure of 2 atm. The process is carried out in 4 stages. First the gas is expanded against a constant pressure of 8 atm, to 8 atm. Then the gas is expanded against a constant pressure of 6 atm, to 6 atm. Then the gas is expanded against a constant pressure of 4 atm, to 4 atm. Finally, the gas is expanded against a constant pressure of 2 þtm, to 2 atm.
