The relationship between the Van-der-Waals model and the undistinguishing statistics of objectively distinguishable objects. The new parastatistics
In the article, the relationship between the mesoscopic picture and the microscopic and macroscopic pictures is considered in the light of the work of V. E. Panin and his school. The coincidence of isochores and isotherms obtained by applying the undistinguishing statistics of objectively distinguishable objects with those of the Van-der-Waals model allows us to specify the heat capacity CV corresponding to real gases. The difference between Gentile statistics and parastatistical models in the mesoscopic case is indicated.
