Hey, I have had a lot of trouble understanding how one obtains a Maxwell relation.
So let's say in general I know(from a specific problem)
T ds = dE - F dL
where F is a tension and L is a length, E is the energy T is the temperature and S is the entropy of a system.
In a specific problem I am asked to compute
ds/dL at constant Temp.
I have an expression for F and it turns out that ds/dL = dF/dT but I don't know how one arrives at this point.
Any help is appreciated, thanks.
