Compressibility Factor

The compressibility factor (Z), is a correction factor which describes the deviation of a real gas from ideal gas behavioriour. It is simply defined as the ratio of the molar volume of a gas to the molar volume of an ideal gas at the same temperature and pressure. It is also known as the compression factor or the gas deviation factor. It is a thermodynamic property for modifying the ideal gas law to account for the real gas behavior.
