Query: The critical compressibility factor value: associative fluids and liquid
  alkali metals   We show how to obtain the critical compressibility factor $Z_c$ for simple
and associative Lennard-Jones fluids using the critical characteristics of the
Ising model on different lattices. The explanation for the results on the
critical point line of the Lennard-Jones fluids and liquid metals is proposed
within the global isomorphism approach.
