The conditions at states 1 and 2 are: Ti = 200 K, pi = 0.1 MPa and T2 = 300 K, p2 = 10 MPa. Level 0 represents the ideal gas limit, where the heat capacity is CP0 = 29.1 J/mole-K
The equation of state of the gas is given by the Van der Waals EOS, Eq (2.5):
pressure pi is calculated by substituting the EOS into the first equality of Eq (6.27) and integrating from p0 ~ 0 where CP = CP0 to p1; the common pressure of states 1 and A:

Do we really want the one thing that gives us its resources unconditionally to suffer even more than it is suffering now? Nature, is a part of our being from the earliest human days. We respect Nature and it gives us its bounty, but in the recent past greedy money hungry corporations have made us all so destructive, so wasteful.
