One mole of an ideal gas is compressed adiabatically in a single stage with a constant opposing pressure equal to 1.00 MPa. Initially the gas is at 27°C and 0.100 MPa pressure; the final pressure is 1.00 MP

a. Calculate the final temperature of the gas, Q, W, ∆U, and ∆H. Do this for two cases : 

Case I. Monatomic gas, Cv = (3/2)R. 

Case 2. Diatomic gas, Cv = (5/2)R. How would the various quantities be affected if n moles were used instead of one mole ?
