105198-01  Clausius, R(udolf).
Ueber die Anwendung des Satzes von der Aequivalenz der Verwandlungen auf die innere Arbeit. SS. 73-112. In: Annalen der Physik und Chemie. Band 116. (22 x 14 cm). (2) X, 644 S. Mit 4 gefalteten lithographierten Tafeln. Interims-Pappband, unaufgeschnitten.
Leipzig, Barth, 1862.
Erste Ausgabe seines vor der Züricher Naturforschenden Gesellschaft gehaltenen Vortrags. - "Clausius began that search for understanding in 1862 by introducing the concept of disgregation, a concept that, he said, was based on an idea he had long held: that the force of heat for performing mechanical work (both internal and external together) was proportional to the absolute temperature. Clausius had never stated this idea explicitly before, although he had argued in 1853, by adopting an analogy between a reversible steam engine and a thermocouple, that the potential difference at a thermocouple junction should be proportional to the absolute temperature. In any event, he now wished to assert that the work which can be done by heat in any change of the arrangement of a body is proportional to the absolute temperature multiplied by a function of molecular arrangement, the disgregation Z. Given this assumption and his postulate that the heat in a body H was only a function of temperature, he was able (1) to prove his theorem of the equivalence of transformations and (2) to separate the equivalence function (entropy) into a temperature-dependent term and a configurational-dependent term" (DSB). - Stellenweise etwas stockfleckig bzw. gebräunt. Einband etwas bestoßen. - DSB 3, 303
