A
For the gas A, a = 0 and its dependence on p is linear at all pressure.
B
For the gas B, b = 0 and its dependence on p is linear at all pressure.
C
For the gas C, which is typical real gas for which neither a nor b = 0. By knowing the minima and point of the intersection with Z = 1, a and b can be calculated.
