What is Compressibility Factor? Explain the Factors which affects Z-value

Compressibility Factor and Factors affects Z-value

Compressibility factor is a measure of deviation of a gas from ideal gas behavior when pressure and temperature changes. It is also called Z-factor and helps to understand how gases behave under different conditions. It is a dimensionless quantity that relates the actual behavior of a real gas to that of an ideal gas.

Compressibility factor is the ratio of the actual volume (V) to the ideal volume (V_ideal) of a gas .
Mathematically, it can be written as-
