The Zeno line is the name given to a line along which the compressibility factor is unity [1]
Batchinsky law[edit]
The Batchinsky law [2], derived from the van der Waals equation of state, states that:
where is the value of the density obtained by the extrapolating the coexistence curve into the low temperature region beyond the triple point, and is the Boyle temperature, which is .
