Employing the ideal gas model, determine the change in specific entropy between the indicated states, in Btu/lbmol?ºR. Solve 2 ways: Use the appropriate ideal gas table AND also by using a constant specific heat value.
a) Air, P1 = 1 atm, T1 = 40 ºF, P2 = 1 atm, T2 = 400 ºF
b) Air, P1 = 20 psia, T1= 100 ºF, P2 = 60 psia, T2 = 300 ºF.
