    Internal Energy as a function of U(S,V,A,Ni)

    Thank you for your reply...what is this technique called? I am working with Legendre transforms and this is similar... Another thing...how can you derive T=partialU/partialS or others without knowledge of the internal energy equation?

    Internal Energy as a function of U(S,V,A,Ni)

    A general thermo question... for the function describing internal energy U(S,V,A,N) U=TS-PV+γA+μN please explain how the total differential is dU=TdS-PdV+γdA+μdN (for a one component system) Basically why is dT=dP=dγ=dμ=0? Is it because they are intensive or potentials...
