Connection between the Isobaric Thermal Expansion Coefficient with the Zeno-Line and Critical-Point Parameters for Liquids

Abstract

We have found the expression which connects the values of volumetric thermal expansion coefficients under low temperatures and pressures with the critical-point and Zeno-line parameters. The calculations based on this expression for different substances (NH(3), CO(2), hexane, Hg, and Cs) are in good agreement with experimental data at relatively low temperatures.
