One of the important approach of the study of real gases involves the analysis of a parameter Z called the compressibility factor `Z=(PV_(m))/(RT)` where P is pressure, `V_(m)` is molar volume ,T is absolute temperature and R is the universal gas constant .Such a relation can also be expressed as `Z=((V_(" m real"))/(V_("m ideal")))` (where `V_("m ideal")` and V_("m real")` are the moler volume for ideal and real gas respectively tendencies among constituent particles.As pressure is force among is lowered or temperature is increased the value of Z approaches ideal behaviour
