5.00 moles of CO2(g) is in a rigid container with a volume of 3.00 liters. The initial temperature is 291 K and the initial pressure is 33.3 bar. Then 4.95 kJ of energy is added to the gas as heat; this raises the temperature to 325 K and raises the pressure to 38.3 bar. CO2(g) can NOT be treated as an ideal gas under these conditions. Calculate )U and )H for the system during this process
