Propane gas at 100°C is compressed isothermally from an initial pressure of 1 bar to a final pressure of 10 bar. Estimate AH and AS. (For data, use the properties of pure species table and the heat capacities of gases in the ideal-gas state table.) The values of the ideal gas constant are given in the table below. (Include a minus sign if required.)
