One mole of an ideal gas at 27°C and 1.00 MPa pressure is expanded adiabatically to a final pressure of 0.100 MPa against a constant opposing pressure of 0.100 MPa. Calculate the final temperature, Q, W, AU, and AH for the two cases, Cv (3/2)R and Cv (5/2)R. [Ans: Case 1 : T2 = 192 K ; Q 0; AU = - W = - 1.35 kJ/mol ; AH = - 2.24 kJ/mol. Case 2: T2 223 K; Q = 0; AU = - W = - 1.60 kJ/mol; AH = - 2.24 kJ/mol ] One mole of an ideal gas at 27°C and 1.00 MPa pressure is expanded adiabatically to a final pressure of 0.100 MPa against a constant opposing pressure of 0.100 MPa.
