Abstract
Within the framework of the Gibbs statistical theory, the issue of the size distribution of particles forming a statistical system and the moments of this distribution are considered. The size distribution of particles and the moments of this distribution are determined from probabilistic considerations. The particle size depends on the interactions in the system, the compressibility factor, the number of interacting particles, and the volume of the system. The relations for the average particle size are substituted into expressions for the intrinsic volume of particles in the equations of state written using excluded volume theory for various expressions for the exclusion factor. The equations of state obtained in this way can be considered as a refinement of the equation of state for dense systems, that is, as a transition to a higher level of description.
期刊介绍：
High Temperature is an international peer reviewed journal that publishes original papers and reviews written by theoretical and experimental researchers. The journal deals with properties and processes in low-temperature plasma; thermophysical properties of substances including pure materials, mixtures and alloys; the properties in the vicinity of the critical point, equations of state; phase equilibrium; heat and mass transfer phenomena, in particular, by forced and free convections; processes of boiling and condensation, radiation, and complex heat transfer; experimental methods and apparatuses; high-temperature facilities for power engineering applications, etc. The journal reflects the current trends in thermophysical research. It presents the results of present-day experimental and theoretical studies in the processes of complex heat transfer, thermal, gas dynamic processes, and processes of heat and mass transfer, as well as the latest advances in the theoretical description of the properties of high-temperature media.
