A) depends on Z and indicated by \[Z=1\]
B) depends on Z and indicated by \[Z>1\]
C) depends on Z and indicated by \[Z<1\]
D) is independent of Z
Correct Answer: C
Solution :
Dominance of strong repulsive forces among the molecules of a gas depend on Z where Z is compressibility factor and it is indicated by \[Z<1\] at moderately low pressure. \[Z=\frac{PV}{{{(PV)}_{ideal}}}=\frac{PV}{nRT}\] for ideal gas \[Z=1,\text{ }Z>1\]for all pressure and temperature is low.
