Ten moles of a gas are cooled at a constant pressure of 20 bar. The initial temperature is 400 K and the final temperature is 300 K. The gas is known to follow the equation of state: V = RT/P + aP2, where a=0.01 L/bar2mol.
A) Prove that (dU/dT)P is equal to CP - P(dV/dT)P. You may use this equality in solving other test problems even if you are unable to prove it. B) Find ?U for the gas in this process. C) Find ?S for the gas in this process. The ACTUAL heat capacity for the gas at the pressure P=20 bar is constant and equal to CP=75 J/mol-K.
