Description of Evaporation Curve for Liquid Metals by the Generalized Van-der-Waals-Berthelot Equation. Part II

In the present work it is shown that the generalized Van-der-Waals-Berthelot equation describes the evaporation curves （saturation curves） for alkali metals with good accuracy. This result is obtained on the basis of the calculations performed by the author for thermodynamic parameters of the saturation curves described by the generalized Van-der-Waals-Berthelot equation.

On the Possibility of an Isochoric Phase Transition in an Electrostatic Field

In the present paper that considers the possibility for modification of equation of state for a non-polar gas in a closed thermally-insulated capacitor and, consequently, the possibility for changing the temperature and pressure under electrostatic field. This can be classified as a new type of phase transitions.

Calculation of Neutron-Proton Mass Difference by the Monte Carlo Method

Calculation results of the Monte Carlo method of the average energy of the electrostatic interaction between the quarks are presented to the neutron and proton. The proposed model of the distribution of quarks in protons and neutrons is possible to assess the area which included a strong (gluon) interaction. Given the fact that the probability of finding a quark in the field with strong interaction is less than one, there is a good agreement between the experimental and calculated values of the mass difference between the neutron and the proton.

Description of Evaporation Curve by the Generalized Van-der-Waals-Berthelot Equation. Part I

The evaporation curve is calculated for the Van-der-Waals and Berthelot gases. It was shown that the evaporation curve of real gases resides between those of Van-der-Waals and Berthelot gases. The generalized Van-der-Waals-Berthelot equation is suggested, which not only qualitatively but also quantitatively describes evaporation curves of real gases. It was also shown that the generalized Van-der-Waals and Berthelot equation well describes other characteristics of real gases.

A Comparison of Different Numerical Schemes to Solve Nonlinear First Order ODE

In this paper, the nonlinear first order ordinary differential equation will be considered. Three simplest numerical stencils are presented to solve this equation. We deduce that the numerical method of Trapezoidal is a good technique, which helped us to find an approximation of the exact solution with small error.

Use of Fossil Energy Will Increase Atmosphere and Earth Land Temperature

Energy used for industrial production, buildings and transport will be accumulated in Atmosphere and Earth land. Global use of energy is known and documented for a long period of time and proportion of fossil and renewable energy is also known. Calculated accumulated energy in Earth land from 1971 to 2018 corresponds to 40% of IPCC Global Energy Inventory and calculated Atmosphere temperature increase from 1971 to 2018 corresponds to 100% of actual measurements.

Anthropogenic Heat Flux Will Affect Global Warming

Examination of 420,000 years old ice cores shows a close relation between temperature increase and CO2-concentration increase. During the industrial era a new energy component appears, Anthropogenic Heat Flux, and a part of that energy will accumulate in Earth climate system and become an essential part of global warming.

Geometrical and Numerical Approach to Solve Transonic Gas Equation

In this paper, the transonic gas equation will be considered. Different methods will be presented and discussed. We will show that there is no unique solution in the computational domain [-1, 1]2?with Dirichlet boundary conditions.
