In this exercise we will utilize the tables for superheatedwater vapor, (D-3). All graphs should be generated using plottingsoftware, e.g. Excel, MatLab, etc. (If you use NIST, do NOT utilizethe built-in plotting software to generate your graphs.) Plot thespecific internal energy and the specific enthalpy Vs T(K) at 1bar. (Use a reasonable number of available temperature values butinclude the maximum and minimum values.) The lower limit of theordinate should be 2500kJ/kg and the lower limit of the abscissashould be 300K. Observe the nature of the relationships and basedon these calculate the ratio of specific heats, gamma. Plot thecompressibility factor as a function of temperature for 1 bar and120 bar and comment on the significance of intermolecular forces.The compressibility factor of a gas is 0.94152 when thetemperature, pressure and specific volume are -50 degree F, 30atmand 0.018317m^3/kg, respectively. Which gas is it?
