In thermodynamics,

Etymology

The term “transformation content energy” is an Hmolpedia coining, a conjunction of the Hermann Helmholtz’s 1882 definition of the quantity ‘–TS’ as bound energy and Rudolf Clausius 1865 labeling of ‘S’ as‘transformational content’ or transformation content.

The derived term ‘transformation content energy’ is useful in modern discussion in the sense that the quantity ‘TS’ is the conjugate variable pair for internal energy changes related to the effects of entropy increase or of the equivalence value of all uncompensated transformations.

**transformational content energy**or "transformational content energy", symbol –TS, refers to the internal energy or total energy changes associated with the transformation content changes accruing during a process or transformation.Etymology
