Entropy in Expansion

Postby Alan Chien 1J » Fri Mar 11, 2016 4:42 pm

During a irreversible expansion and an irreversible free expansion, do the two different methods affect the entropy? I realize entropy is a state function so the two would be the same but would the free aspect of the second expansion affect the entropy of the system or surroundings in any way differently than the first expansion?

Nah, the main thing about free expansion is that it doesn't do any work.

I don't think that it would be any different. Because entropy is a state function it is dependent on only the initial and final states and therefore the path taken and work done in the process does not matter.
