For the gas A, a = 0 and its dependence on P is linear at all pressures

For the gas B, b = 0 and its dependence on P is linear at all temperatures

For the gas C, which is typical real gas for which neither a = 0 nor b = 0, by knowing the minima and the point of intersection, with Z = 1, a and b can be calculated

At high pressure, the slope is positive for all real gases
