Remarks on Irreversible Processes and Entropy Increase



B Robertson


Thermodynamics defines entropy only at equilibrium and says that, for an isolated system that undergoes an irreversible process, the entropy is increased. It is silent about whether entropy increases monotonically during the irreversible process. Thus it does not disprove an expression for nonequilibrium entropy just because the expression may increase non monotonically. Remarks on the information entropy maximization method and extended thermodynamics by B.C. Eu (submitted to J. Chem. Phys.) are analyzed.
