When is ∆S surroundings = 0?
Is it for any irreversible expansion or solely irreversible free expansions? And does this irreversible expansion have to be isothermal?
∆S surroundings ?

Re: ∆S surroundings ?
deltaS of the surroundings is 0 for all irreversible expansions/compressions. Free expansions do no work (since the expansion occurs against an external pressure of 0) and are adiabatic so q=0 as well. Since there is no energy transfer between the system and the surroundings, delta S of the system, surroundings, and universe is 0. Correct me if I am wrong anyone, but hope this helps!
