4. A constant pressure process of an ideal gas starts at -10C and 150 kPa and ends when the volume is four times its original value. The mass of gas is 1.533 kg. This gas has a molecular weight of 31 and cp = 1.162 and cv = 0.894 kJ/kgK. R= 8.314 kJ/kmol K= 1545 ftlbf/IbmolR a. Find the volume occupied by the gas at the initial state (m) (10 points). b. Find the temperature at state 2 (C) (10 points). c. Find the change in enthalpy for this process (kJ) (10 points). d. Find the heat transfer for this process (kJ) (10 points)
