The Zeno line is the name given to a line along which the compressibility factor is unity [1]

Z:= \frac{pV}{Nk_BT}=1

Batchinsky law[edit]

The Batchinsky law [2], derived from the van der Waals equation of state, states that:

\frac{\rho}{\rho_B} + \frac{T}{T_B} = 1

where \rho_B is the value of the density obtained by the extrapolating the coexistence curve into the low temperature region beyond the triple point, and T_B is the Boyle temperature, which is a/bR.
