Nonideal (Real) Gases
A useful measure of how much a gas deviates from
ideal gas behavior is found in its compressibility factor.

The compressibility factor of a gas is the PV/nRT ratio.
For ideal gases PV/nRT = 1
For a real gas, the compressibility factor can have
values that are significantly different from 1
