The Generalized Van-der-Waals-Bertlo Equation. Part III. Description of the Dependence of the Dielectric Permeability of Gas on Temperature and Pressure | Chapter 4 | Newest Updates in Physical Science Research Vol. 14

 In this study, we look at how to use the equation of state for model gases to describe experimental dielectric permeability dependencies on pressure and temperature for nonpolar gases. The instance of argon is used as an illustration. The generalised Van-derWaals-Berthelot equation is shown to accurately characterise the dependency of dielectric permeability on pressure and temperature. It is demonstrated that utilising isotherms with modest temperature increments to assess dielectric permeability yields the exact tabulated equation of state. This finding can be used to other fields of research.

“The Generalized Van-der-Waals-Bertlo Equation” (Part I): Description of the Gas Evaporation Line | Chapter 5 | Newest Updates in Physical Science Research Vol. 14

 Only the Van-der-Waals and Berthelot equations, as well as their generalisations, are considered in this study. The evaporation curves for the Van-der-Waals and Berthelot gases are calculated. The evaporation curve of actual gases was found to lie somewhere between that of Van-der-Waals and Berthelot gases. The generalised Van-der-Waals-Berthelot equation is proposed, which qualitatively and quantitatively characterises evaporation curves of actual gases. The generalised Van-der-Waals and Berthelot equation was also shown to appropriately represent other real-world features.

The Generalized Van-der-Waals-Bertlo Equation. Part II. Description of the Line of Evaporation of Alkaline Metals| Chapter 6 | Newest Updates in Physical Science Research Vol. 14

 In this study, the generalised Van-der-Waals-Berthelot equation is shown to appropriately characterise alkali metal evaporation curves (saturation curves). The author's estimates for the thermodynamic parameters of saturation curves described by the generalised Van-der-Waals-Berthelot equation are used in this analysis. The findings show that the generalised Van-der-WaalsBerthelot equation accurately explains the evaporation curves for alkali metals (about several percent)
