entropy is a chemist's portion of the internal energy
Sorry, that's not right.
Entropy is not a form of energy. It doesn't have units of energy. It does
not stand in a one-to-one relation with energy. It obeys a subconservation
law which neither implies or is implied by the energy conservation law. It
is important to physicists, computer engineers, electrical engineers,
librarians and others -- not just chemists.
