The new equation for «apparent» heat of vaporization

Kudryavtseva I.V., Rykov A.V., Rykov V.A.

On the basis of the analysis of the equation of Klapejrona-Klauziusa the new equation for «apparent» heat of vaporization, physically proved for a wide neighbourhood of a critical point is gained. Thermodynamic tables are calculated on lines of phase equilibrium of the argon, including pressure, density, heat of vaporization, the first and second derivative of pressure on elasticity lines on temperature.
