Entropy of Surroundings vs. System
How do we know when the entropy of the surroundings is positive or negative in a volume expansion?

∆S = nR lnV2/V1
From the equation above, I believe you can find that when calculating for the entropy of a system itself, if V2 is greater than V1, the deltaS value will be greater than if V1 > V2. (This indicates expansion). If entropy of the system is increasing, then entropy of the surrounding would have to decrease and vice versa.

if the entropy of surroundings is positive that means there is more and vice versa.

Logically, a volume expansion would mean that there are technically more microstates for a system to have, and so entropy would increase.
