WebAs Nick says, the second equation states the fact that the total differential of a two-variable function can be written as d S ( T, V) = ∂ S ∂ T d T + ∂ S ∂ V d V. The first equation is the fundamental thermodynamic relation for a closed system (can exchange heat but no diffusion of particles): d U = T d S − P d V. If an infinitesimally small amount of heat is supplied to a system in a reversible way then, according to the second law of thermodynamics, the entropy change of the system is given by: Since where C is the heat capacity, it follows that: The heat capacity depends on how the external variables of the system are changed when the …
