Entropy of Irreversible Processes across a Boundary | Chapter 13 | New Insights into Physical Science Vol. 11

Different from the traditional theory of irreversible thermodynamics, a novel approach has been provided for calculating the entropy associated with irreversible processes. It allows for a clear relation, in terms of observable properties, between heat and work transfers in irreversible processes and those in reversible changes. The same technique is applied to thermodynamic state construction

Functions which are not limited to reversible phenomena anymore. The results are then used to create line integrals associated with the flow of heat, function, and matter across a junction for the contribution of irreversible processes to the entropy. Relevant examples are given to explain the procedure; they relate to temperature and volume changes and to the cycling of systems across a thin membrane communicating with a reservoir.
