The compressibility factor for an ideal gas is

The value of compressibility factor for an ideal gas is equal to 1.

The gases obey the different gas laws only theoretically. Practically all of them show some deviation from these laws. These are called real gases. The deviation are maximum under high pressure and at low temperature. These are comparatively small when the conditions are reversed. It has been found that the easily liquefiable gases show more deviations from the ideal gas behaviour as compared to the gases which are liquified with difficulty. The compressibility factor for an ideal gas is :
