WebE = internal energy (arising from molecular motion - primarily a function of temperature) + kinetic energy + potential energy + chemical energy. Defines a useful property called "energy". The two new terms in the equation (compared to what you have seen in physics and dynamics, for example) are the internal energy and the chemical energy. The internal energy of a system depends on its entropy S, its volume V and its number of massive particles: U(S,V,{Nj}). It expresses the thermodynamics of a system in the energy representation. As a function of state, its arguments are exclusively extensive variables of state. Alongside the internal energy, the other cardinal function of state of a thermodynamic system is its entropy, as a function, S(U,V,{Nj}), of the same list of extensive variables of state, except that the entropy, S, …
