**Compressibility**

Thermodynamicists use this factor (*Z*) to alter the ideal gas equation to account for compressibility effects of real gases. This factor represents the ratio of actual to ideal specific volumes. It is sometimes referred to as a "fudge-factor" or correction to expand the useful range of the ideal gas law for design purposes. *Usually* this *Z* value is very close to unity. The compressibility factor image illustrates how Z varies over a range of very cold temperatures.
