The compressibility factor, \(Z=\dfrac{pV}{nRT}\) is defined for gases, \(R\) being the universal gas constant & the remaining quantities \(p,V,T,n\) being defined using standard notation. A graph of \(Z\) versus pressure \(p\) is shown for gases \(A\) & \(B\) at moderate temperatures \(T_1\) & \(T_2.\)
The value of \(Z\) for an ideal gas would be:
