New Thermodynamics: Reversibility, Entropy and Adiabatic Processes


  •   Kent W. Mayhew


Accepted assertions concerning entropy and reversibility in both isentropic and adiabatic processes will be investigated and challenged. The ultimate conclusion being that accepted thermodynamics is an over-complication.

Furthermore, the need for natural logarithmic functions will be explained. This functionality no longer depends upon entropy, whatever entropy’s true guise turns out to be. Moreover, it will be discussed how isothermal entropy change is embedded in circular logic.

Keywords: entropy, reversibility, adiabatic, isentropic, circular logic
