- Intensive quantity + (Intensive quantities are partial derivativ … Intensive quantities are partial derivatives of an extensive quantity by the advancement, d<sub>tr</sub>''ξ''<sub>''X''</sub>, of an energy transformation tr; ''example:'' [[Force]]. In contrast to [[extensive quantity |extensive quantities]] which pertain to the entire system and are additive, extensive quantities 'take well defined values at each point of the system' ([[Prigogine 1967 Interscience]]) and are non-additive. Intensive and extensive quantities can be easily discriminated by the units, e.g. [J] for the extensive quantity, in contrast to [J·mol<sup>-1</sup>] for the corresponding intensive quantity. In the general definition of thermodynamics, intensive quantities are not distinguished from [[specific quantity |specific quantities]] ([[Cohen 2008 IUPAC Green Book]]). [[Ergodynamics]] emphasizes the contrast between specific quantities which are extensive quantities normalized for a variable expressing system size (mass, volume of the system, amount of substance in a system) and intensive quantities which are normalized for the motive unit of a transformation (mass exchanged, volume change of the system, amount of substance reacting in a system; [[Gnaiger 1993 Pure Appl Chem]]). Intensive and specific quantities are both non-additive, take well defined values at each point of the system, and both corresponding quantities are expressed in identical units, e.g. the intensive quantity Gibbs force of a catabolic reaction (such as oxidation; 0 = -1 Glc - 6 O<sub>2</sub> + 6 CO<sub>2</sub> + 6 H<sub>2</sub>O), Δ<sub>k</sub>''G''<sub>Glc</sub> [kJ·mol<sup>-1</sup>], and the specific quantity Gibbs energy per mole glucose contained in a system, ''G''<sub>Glc</sub> [kJ·mol<sup>-1</sup>] (with respect to an arbitrarily defined reference state, such as the reference state of formation or combustion).<sub>Glc</sub> [kJ·mol<sup>-1</sup>] (with respect to an arbitrarily defined reference state, such as the reference state of formation or combustion).)
