I Entropy statement question

  1. Apr 23, 2016 #1
    For all adiabatic processes the entropy of the system does not change (speaking in general) Is this statement correct?

    That statement is not correct. Entropy can be both transferred with heat and also generated by irreversibilities within the system. Adiabatic processes eliminate the first possibility.

    In other words, the entropy of the system does not change for an adiabatic reversible process.
