## Abstract

It is shown that the “meso-phase” hypothesis of Woodcock L. V. fails to describe quantitatively and qualitatively the isochoric and isobaric heat capacities, speed of sound, long wavelength limit of the structural factor, isothermal compressibility, density fluctuations, Joule–Thompson coefficient and isothermal throttling coefficient of argon in the “meso-phase” region. It is also shown that VdW-EOS can describe qualitatively the excess Gibbs energy and rigidity of argon near-critical point.
