Is there a missed relationship between entropy and kinetic theory of gases? a new perspective for the instruction

Abstract

This paper is concerned with the investigation for finding missed models that combining between thermodynamic and kinetic theory of gases. The research was initiated by supposing a fixed number of molecules at gas state in a closed box of two equivalents parts. When the barrier between those two parts is removed, the volume of the box will be double of the first stage. It was concluded that the present study gives confirmation for the already existing models with no new developed model unless the employment of Charles's law in derivation process, in spite of the last law is proper for ideal gas rather than the proposed real gas. The derived model of entropy (ΔS) using the last law gives the same value of ΔS that calculated from the standard model. The presented article can be considered as a good exercise for students in order to get an idea of how one could think for connect two different subjects for developing new models which could help in understanding the scientific theories and also in opening new doors of science.
