One kilogram of carbon dioxide (CO2) gas (M = 44.01 kg/kmol) is filled in a frictionless piston-cylinder assembly. The piston can move freely in the cylinder and it is in surroundings of 1 atm. Initially, the CO2 is at 400 K and 1 atm. Heat transfer to the CO2 occurs until the final temperature is 800 K.
a) Is the ideal gas model applicable for both the initial and final states of the CO2 gas? (You must show your work to justify your answers).
b) Assuming the ideal gas model is applicable, determine the heat transfer for the process. (Do not assume constant cv and cp)
