Rediscussion on gas-liquid phase transition
Yuan-Xing Gui
Liquid-gas phase transition in statistical mechanics is a long-standing dilemma not yet well explained. In this paper we propose a novel approach to this dilemma, by: 1). Putting f…
Gas-Liquid Phase Transition in Statistical Mechanics
Yuan-Xing Gui
A new theory on gas-liquid phase transition is given. The new idea is that the total intermolecular potential energy for a classical system in equilibrium is relative with the aver…
Modification to the Van der Waals Equation of State
Jianxiang Tian, Yuanxing Gui
In this paper, we modify the VDW equation of state by adding a temperature factor to it. As a result, we give out a good phase diagram and the correlation of the reduced pressure a…
An Assumption About The Free Energy Near The Critical Point
Jianxiang Tian, Yuanxing Gui
We divide the free energy near the critical point into two parts. One is the regular part, the other is the singular part. The singular part is assumed to be a concrete possible fo…
