# Ideal Gas Law with Compressibility Factor

Written by Jerry Ratzlaff on . Posted in Thermodynamics

The ideal gas law with compressibility factor is used for higher pressure and temperature than the ideal gas law that is at atmospheric conditions.

## Ideal Gas Law with Compressibility Factor formula

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

### Where:

$$\large{ p }$$ = pressure of gas

$$\large{ z }$$ = compressibility factor (1.0 is the ideal gas)

$$\large{ n }$$ = number of moles of gas

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

$$\large{ T }$$ = temperature of gas

$$\large{ V }$$ = volume of gas
