    What is the value of change in entropy (S2-S1) for irreversible adiabatic process?

    This sounds like a homework question. We discourage members providing other members with answers to homework questions.

    Members will be happy to help you if you show that you have made some effort to answer the question yourself. Have you?

    Then please don't muddy the water. The simplest way of saying what the question is about is to note that the OP wishes to know the value in the change in entropy (S3-S1) for an irreversible adiabatic process.

    If the work addition in the process is entirely against friction or resistance, the entropy increase is dw/T but not all work may be converted. Reversible work does not increase entropy.
