A 100L cyclinder in at 100C contains N2 gas, and H2O gas which is just saturated, with total pressure at 135kPa. when the cylinder is compressed at constant temp. reversibily to total pressure 169kPa. Given the saturated vapour pressure of water is 101kpa at 100C and molar  heat of vaporization of water is 40.7 KJ/mol.
Calculate change of U, H, A (A=U-TS), G, and S.
