On classical and modern approaches to the second law of thermodynamics and phase equilibrium
https://doi.org/10.22349/1994-6716-2019-99-3-29-37
Abstract
The paper presents authors’ comparison and short analysis of currently accepted and classical approaches to the second law of thermodynamics and phase equilibrium, as well as short comments on the discrepancies. It has been noted that during physicochemical processes, even an ideal mixing (when there is no visible release/absorption of heat) could not go without hidden self-compensating energy processes inside the system. Energy emission happens due to the strengthening of interatomic bonds and its simultaneous absorption due to the increase of the oscillation energy (work done by a system), i.e. of the average heat capacity.
