Aggiungi al carrellohardcover. Condizione: very good. first edition. In-octavo demi-basane d époque, rousseurs légères , 448 pp In: "Annales de Chimie et de Physique", 2e series, tome 74. 448 pp., 1 folded plate. Hess' paper: pp. 325-335 First edition of Hess's most famous paper, in which he outlined his law on thermochemistry. His principle, a pro…genitor for the first law of thermodynamics, came to be called Hess's law. It states that in a series of chemical reactions, the total energy gained or lost depends only on the initial and final states, regardless of the number or path of the steps. This is also known as the law of constant heat summation. Hess described here his newly discovered law, known as Hess's Law, in form of a letter to Arago. (The letter was also published in Comptes Rendus in a slightly modified form). "Here thermochemistry received its first importent advance at the hands of Germain Hess, who showed that the heat evolved in a reaction is the same regardless of whether the reaction is carried out directly or in a number of steps." (Leicester & Klickstein "A Source Book in Chemistry", pp. 329-332). This paper preceded the larger papers also published in "Annales de Chimie et de Physique" and the original (and larger) paper in "Bulletin scientifique, Academie impériale des Sciences (St. Petersbourg, 1840)". The volume contains also papers by Laurent, Biot, Mulder, Melloni etc.Parkinson "Breakthroughs" 1840.

First edition in French of Hess' first fundamental law in thermodyn…amic: "the law of heat formation" (1840), anticipating a specific example of the "LAW OF THE CONSERVATION OF ENERGY", 2 years before Julius Robert Mayer elucidated the more general principle in 1842 - claiming that "the heat developed in chemical change is constant, whether the change occurs directly or indirectly in several stages"Germain Henri Hess is noted today for two fundamental principles of thermochemistry: the law of constant summation of heat (known simply as Hess's law) and the law of thermoneutrality. These discoveries were remarkable in that they were postulated without any supporting theoretical framework and took place in a field of study almost totally neglected by his contemporaries. Hess's law is of immense practical importance and is used to this day to determine heats of reaction when their direct measurements are difficult or impossible. (Chemistry Encyclopedia)."Numerous men, notably Lavoisier and Laplace had measured the heats evolved in various reactions, but thermochemistry received its first importent advance at the hands ofgermain Henri Hess, who showed that the heat evolved in a reaction is the same regardless of whether the reaction is carried out directly or in a number of steps. This generalization, known now as "Hess's Law", makes possible the calculation of heats for many reactions where direct measurement are impracticable."(Leicester & Klickstein, A Source Book., p329."The thermochemical work of Hess was continued extensively in the second half of the nineteenth century through the studies of Thomsen and Berthelot. Both Berthelot?s principle of maximum work and the thermodynamic theories of affinity which came to prevail were clearly foreshadowed in the work of Hess. In addition to his internationally known research in thermochemistry, Hess was very influential in the development of chemistry in Russia. His text Osnovania chistoy khimii (Fundamentals of Pure Chemistry) went through seven editions and did much to establish the chemical nomenclature of the Russian language. He was always interested in technological questions, and many of his students later contributed to Russia?s industrial development."
