(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Consider the following equality:

([itex]\frac{∂S}{∂V}[/itex])_{T}= ([itex]\frac{∂P}{∂T}[/itex])_{V}

If I rearrange the equality so that I write:

([itex]\frac{∂S}{∂P}[/itex])_{?}= ([itex]\frac{∂V}{∂T}[/itex])_{?}

What variables will be constant in each side?

I'm having some trouble in a few thermodynamics problems because of this...

2. Relevant equations

3. The attempt at a solution

I don't know how to do this. Normally I just ignore and assume that every variable except the variable of differentiation is a constant.

If anyone could confirm or correct me I'd be thankful.

Thanks.
