    sir delta S zero nhi hoga reversible process ke liye??

    eduncle-logo-app

    Change in entropy for a reversible process is not necessarily zero. For a reversible process dS=dQ/T In general, Change in entropy=dQ/T + Entropy generation (due to irreversibility) This entropy generation is path dependent (may be +ve/-ve/zero), for reversible path it is zero. Therefore, 1. For a reversible process, Entropy change is zero iff it is adiabatic. 2. For any process (reversible/irreversible), Entropy change may be +ve/-ve/zero.

    means for reversible process delta S is zero only when process is adiabatic
