Compressibility is a measure of the relative volume change of fluid or solid or gas as a response to a pressure or temperature change.
The compressibility factor is defined as
where, p is the pressure, V is the molar volume of the gas, T is the temperature, and R is the gas constant.
To understand the extent of deviation a graph of Z vs p is plotted. The graph will be a straight line parallel to pressure axis for ideal gases. But gases which deviate from ideality, the value of Z will deviate from unity(i.e. 1). At very low pressures all gases shown to have Z ≈1 and behave as ideal gas.
