Evaluate the internal energy amd ethalpy changes

Reference no: EM13647620

Calculate the internal energy amd ethalpy changes that occur when air is changed from an initial state of 40 0F and 10 atm, where its molar volume is 36.49 (ft)3 (lbmol)-1 to a final state of 140 (0F) and 1 atm. Assume for air that PV/T is constant and that Cv=5 and Cp=7 (Btu)(lbmol)-1 (0F)-1.
