∵Z=‌

pV

nRT

where,
Z= compressibility factor,
p= pressure
V= volume, n= number of moles
R= gas constant,
T= temperature,
Also, curves for (Z vs p)
(i) If Z>1 the gas show positive deviation from ideal behaviour and is less compressible.
(ii) If Z<1, gas show negative deviation.
(iii) No, real gas give a straight line parallel to (p).
i.e. path way (2) and (3) only.
