Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

got this reshav??

sir delta S total for reversible processes clzero nhi hota hai kya
![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 entropy change is zero only when process is adiabatic
