Applied Physics and Mathematics Annotation << Back THERMODYNAMIC EQUATION OF REAL GASES P.V. FEDOTOV In the proposed article, a comparative analysis of the equations of state of gases in molecular physics and the equations of thermodynamics is carried out. On the basis of the analysis carried out and the identification of relationships, a new thermodynamic equation of state for real gases is proposed, which combines gas and thermodynamic parameters. The necessity of including the energy of electromagnetic radiation during phase transitions into the equation of state of real gases is also shown. Keywords: Klaiperon-Mendeleev equation, equations of state of real gases, thermodynamic potentials, electromagnetic radiation during phase transitions. DOI: 10.25791/pfi m.06.2023.1279 Pp. 08-15.
