we received theoretical formulas of the interconnection between melting, boiling and critical temperatures. Uniform physical representation of melting, boiling and evaporation processes was the basis for deriving the formula of interconnection between them. We use the concept of the material substance internal energy in terms of the molecules “unpacking” idea. The reference manual data on 85 substances from 13 to 855 degrees Kelvin confirms the theoretically derived formulas. We carried out the comparison of theoretical formulas and experimental data by their mean values. A simple ideal substa...
according to the properties of melting points and boiling points of the elements of the periodic table of D.I. Mendeleyev the application of the unpacking hypothesis of the substance was verified. The article contains the results of the verification. In general, according to the data for 98 substances taken from the information in Internet, convergence of results with an error of up to 40% for 73 substances was obtained. The effect of periodicity on the result is found. An exception to the calculated dependences was obtained for ten substances: noble gas and most halogens. A large discrepancy...
based on the physical model of «unpacking» a fluid, published in 1983 to explain the physical nature of surface tension, an explanation of capillary phenomena was proposed. The unified physical nature of the condensation process and the processes in the capillaries expressed in terms of the surface tension of the liquid is proved. To prove the applicability of the «unpacking» model for capillary phenomena, an empirical Borelli-Jurin formula for determining the height of fluid lifting in capillaries was theoretically derived depending on the magnitude of the surface tension. The assumptions und...
this article brings together previously published evidence of the unified nature of physical processes and phenomena in terms of changes in the energy of a substance molecule. The unified physical nature of all these physical phenomena has been proven, as a single multistage process of energetic unpacking of molecules of a substance, which is logical to call the molecular-energy concept of unpacking a substance.
The considered processes include the following processes. Surface rupture, characterized by the surface tension coefficient. The melting process of a substance characterized by its mel...
в данной статье на основании молекулярно-энергетической концепции распаковки вещества рассмотрен взгляд на температуры плавления, кипения и критическую для вещества с точки зрения изменения энергии молекулы вещества. Показана теоретическая взаимосвязь каждой из этих температуры со скрытой теплотой плавления. Результаты этой взаимосвязи доведены до расчетных формул. Полученные формулы подтверждены данными из справочников и известными эмпирическими зависимостями. На основании анализа справочных данных сделан вывод о скрытой теплоте плавления, как части внутренней энергии вещества.
Таким образом...
A theoretical estimate of the dependence of ultimate strength on the physical properties of a solid substance—such as density, molecular weight, melting point, and enthalpy of fusion—has been obtained. This dependence explains how these properties influence the material’s strength based on the “unpacking” concept of substance matter. The physical limits of applicability for the concept of “force” in Newtonian mechanics, and its distinction from the “unpacking” concept, are substantiated.
This dependence, while similar in form to the Clapeyron-Mendeleev equation for an ideal gas, has a differen...
