He assumed that whatever the actual patterns on intermolecular forces, one could suppose that there is some advantage distance between the centers of molecules which would represent a general boundary between attractive and repulsive forces. If two molecules were to approach each other within that boundary, repulsion would generally occur. Thus the very complex problem of intermolecular action was reduced to a ""billiard ball"" model.""

‎First appearance of the paper in which Clausius makes importent contributions to the generalization and understanding of the Second Law of Thermodynamics by introducing the concept of disgregation and proving the equivalence of the transformation of heat.""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.13 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).The issue contains other notable papers, Plücker ""Ueber recurrente Ströme und ihre Anwendung zur Darstellung von Gasspectra"", pp. 27-54, Tyndall ""Ueber Strahlung und Absorption der Wärme durch gasförmige Materie"", pp. 1-27.‎

‎First French version of this milestone paper on the Kinetic Theory of Gases - ""Ueber die Art der Bewegung, welche wir Wärme nennen"", 1857 - in which Clausius gives the physical explanation for the evaporation of a liquid and presents the first physical argument in support of Avogadro's hypothesis that equal volumes of gases at the same temperature and pressure contain equal numbers of molecules.""In the paper ""Ueber die Art der Bewegung, welche wir Wärme nennen."", Rudolf Clausius (1822-1888) established mathematically that the heat in a gas cannot be accounted for exclusively by translational motion of the molecules and asserts that molecules have rotational and vibratiional motion as well as translational motion. He consequently rejects the contentions the the translational kinetic energy is conserved during molecular collisions and that all molecules have equal, constant velocities. His allowancee for differing molecule velocities enables him to offer a new explanation of evaporation, asserting that he molecules able to overcome the attractive forces of the liquid and ""escape"" to the gaseous state are those with high velocities (and hence high kinetic energies). hence evaporation produces a loss of energy in the liquid and a decreasein temperature.""(Parkinson in ""Breakthroughs"", 1857 C/P).""This 1857 paper (the paper offered) also marked another importent beginning in physical theory, for it presented the first physical argument in support of Avogadro's hypothesis that equal volumes of gases at the same temperature and pressure contain equal numbers of molecules. Clausius argued that if it were assumed that all types of molecules possess the same translational energy at equal temperatures, then, since all gases have the same relationship between pressure, volume, and temperature, they would necessartly contain equal numbers of molecules in equal volumes at the same temperatur and pressure. Avogadro's hypothesis, therefore, found support in the mechanical theory of heat, independently of the usual chemical arguments.""(DSB III, p. 307).The volume contains JOULE'S famous paper ""Remarques sur la nature de la chaleur et la constitution des fluides élastiques"" (Extraits par M.

His reply to Clausius contains very importent additons to his conservation law, as it clarifies his use of the concepts of ""energy"", ""vis viva"", ""electrical tension"" , ""potentials"" etc.Helmholtz famous work Über die Erhaltung der Kraft"" from 1847 gave the first comprehensive statement of the first law of thermodynamics: All modes of energy, heat, light, electricity, and all chemical phenomena, are capable of transformation from one to the other but are indestructible and cannot be created. Clausius (in the papers offere) critized helmholtz on his theory of heat over the consistency of the physical interpretation and of the use mathematics. He argued that Helmholtz's demonstration of his conservation law was valid only for Helmholtz's particulat model of matter, and that he had not understood the notion of the potential. This criticism lead Helmholtz expand and clarify the central concepts of physics, importent steps in the history of theoretical physics.‎

‎First printing of this importent paper, the seciond of C's papers in the working out of the Kinetic Theory of Gases. In the paper he states that he found an error in Maxwell's theory of gases, an error Maxwell was to admit as far more serious. ""In his initial approach to the conduction of heat in gases, Maxwell drew a brilliant analogy between diffusion (a transfer of mass) and conduction (a transfer of kinetic energy), thereby making it possible to use the form of his diffusion equation to represent conduction, simply replacing the mass of a molecule with its kinetic energy. Clausius critized this adoption of the diffusion equation, because, given the assumptions, mass transfer would accompany the heat conduction and the process would not be one of energy transfer alone. He then offered a revised theory of conduction. ""(DSB III, p. 308).""Clausius was one of the founders of the kinetic theory of gases and of the science of thermodynamics.

‎Quelques figures dans le texte en noir 1ere édition, édition originale en français, 1868 "Contents, Chapitres : Préface du traducteur, préface de l'auteur, xxiv, Texte, 441 pages, catalogue Lacroix, 36 pages - - Rudolf Julius Emmanuel Clausius (Köslin, Poméranie, 2 janvier 1822 Bonn, 24 août 1888) est un physicien allemand connu pour ses contributions majeures à la thermodynamique. Découvrant au hasard de ses recherches l'ouvrage oublié ""Réflexions sur la puissance motrice du feu"" de Nicolas Léonard Sadi Carnot, il en comprit immédiatement la portée et en assura la promotion auprès des physiciens de son époque. Il complète l'énoncé de la deuxième loi de la thermodynamique (1850), et inventa le concept d'entropie en 1865. Il est reconnu sur le plan international comme le véritable énonciateur du second principe de la thermodynamique puisque ayant introduit la notion d'entropie toujours utilisée aujourd'hui. Clausius justifie son choix dans Sur diverses formes des équations fondamentales de la théorie mécanique de la chaleur (1865) : « Je préfère emprunter aux langues anciennes les noms des quantités scientifiques importantes, afin qu'ils puissent rester les mêmes dans toutes les langues vivantes ; je proposerai donc d'appeler la quantité S l'entropie du corps, d'après le mot grec (...) une transformation. C'est à dessein que j'ai formé ce mot entropie, de manière qu'il se rapproche autant que possible du mot énergie ; car ces deux quantités ont une telle analogie dans leur signification physique qu'une analogie de dénomination m'a paru utile ». (cité dans Dictionnaire d'histoire et de philosophie des sciences de Dominique Lecourt, PUF, 1999). Ses travaux sur la thermodynamique lui valurent la médaille Copley en 1879.
