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 Following graph represents a pressure (P) volume (V) relationship at a fixed temperature (T) for moles of a real gas.The graph has two regions masked (I) and (II). Which of the folloingoption true ?

Which of the folloingoption true ?
Answer» `Zlt1` in the region (II) Z = 1 in the region (II) Z = 1 for the curve Zapproaches 1 as we MOVE from region (II) region(I) ANSWER :D
