6 kg of an ideal gas is in a volume of 1 m3 at 250°C. The gas undergoes a constant pressure change of state until the temperature is 500°C.
a. Find the pressure at the initial state (MPa).
b. Find the volume at the final state (m3).
c. Find the change in enthalpy of the process (kJ).
d. Find the heat transfer for this process (kJ).
