Compressibility factor
From SklogWiki
The compressibility factor, \(Z\), is given by
\[Z=\frac{pV}{Nk_BT}\]
where p is the pressure, V is the volume, \(k_B\) is the Boltzmann constant, T is the temperature and N is the number of molecules.
[edit] Compressibility factor of an Ideal Gas
From the ideal gas law we see that
\[Z= \frac{pV}{Nk_BT}=1\]
