One of the important approach to the study of real gases involves the analysis of 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 molar volume for ideal and real gas respectively). Gas corresponding Z lt 1 have attractive forces amoung constituent particles. As the pressure is lowered or temperature is increased the value of Z approaches 1. (reaching the ideal behaviour) For a real gas G Z gt 1 at STP Then for 'G': Which of the following is true:
