I don't think it means volume is equal to work, but work is measured in the change in the volume of a system (the work done by the system or the work done to a system). I believe it is related to the relation q=-w, which is equal to nRT ln V2/V1. I believe thats how the W2/W1 becomes the V2/V1 in the equation.

But I don't think W is work? It's the W for degeneracy I believe

Hey Teresa!

W is the degeneracy. Degeneracy identifies how many different configurations there are that have the same energy.

Therefore, you can imagine that if I double the volume of a gas I double the amount of configurations the molecules could obtain.
