Talk:Disgregation

Note

For those interested, the original manuscript has about 10-15 pages worth of mathematical derivation in which Clausius derives the second law by letting: Z be the disgregation of the body, and dZ an infinitely small change of it, and let dL be the corresponding infinitely small quantity of work, we can then put: dL = KTdZ; where where K is a constant depending on the unit, hitherto left undetermined, according to which Z is to be measured. You can read parts of the derivation here (see #5 & #7). --Sadi Carnot 11:14, 28 October 2006 (UTC)

Disgregation is not a precusor of entropy concept, it is a component of it

This Wikipedia article reads as if the concept of digregation is a rudimentary precursor of the fully fleshed out concept of entropy. This is completely wrong. Clausius's concept of disgregation was a component of his full understanding of entropy. Clausius divided entropy into two components: (1) the transformational value of the kinetic energy of the particles of the system, and (2) the transformational value of the potential energy of the arrangement of the particles (due to intermolecular forces attracting the molecules to one another). Gibbs himself discussed the concept of disgregation with approval, and clearly understood it was a component of overall entropy. This article should be updated to reflect the correct understanding of disgregation, which is still valid today. An excellent discussion of the concept, and Gibbs's approval of it can be found in this paper: "Gibbs on Clausius" (at https://www.jstor.org/stable/pdf/27757297.pdf - the online version can be read for free with registration). — Preceding unsigned comment added by Nickg (talk • contribs) 18:44, 18 July 2019 (UTC)
