Entropy change of an irreversible process

  1. Dec 10, 2007 #1
    Can entropy change be zero for a closed system in an irreversible process? If yes under what conditions? Thanks!

    As far as classical thermodynamics is concerned, the entropy change will always be zero for an irreversible process in a closed system.

    I am shocked!

    While browsing through some old posts, I stumbled upon this, and I got a terrible shock. :eek: I had made a typo and nobody had commented on it. My apologies to the OP. What I had meant to write was:

    As far as classical thermodynamics is concerned, the entropy change will always be greater than zero for an irreversible process in a closed system, and zero for a reversible process in a closed system.
