# Gas Compressibility Factor

Written by Jerry Ratzlaff on . Posted in Thermodynamics

The gas compressibility factor, abbreviated as Z, is a dimensionless factor independent of the quantity of gas and determined by the character of the gas, the temperature, and pressure.

### Gas compressibility factor formula

$$\large{ Z = \frac{p \; V}{n \; R \; T} }$$

Where:

$$\large{ Z }$$ = gas compressibility factor

$$\large{ n }$$ = moles

$$\large{ p }$$ = pressure

$$\large{ R }$$ = specific gas constant

$$\large{ T }$$ = temperature

$$\large{ V }$$ = volume
