Hardcover. Condition: Good. Nicolas CLEMENT, Benard DESORMES. "Détermination expérimentale du Zéro absolu de la chaleur et du caloriques spécifique des Gaz" in Bibliotheque Universelle, Geneva, 1820, volume 13, pp 95-111. "In a second publication (Gay-Lussac, 1818) Gay-Lussac analyzed the production of cold by the expansion of a gas. He realized that cooling by evaporation was limited and pointed out that the minimum temperature achieved was only 80°C. He believed that it was possible to achieve lower temperatures by using the equivalence between cooling caused by the expansion of a gas and heating caused by compression. It was known that compressing the air to one-fifth of its original volume increased the temperature 300°C and Gay-Lussac thought that the temperature might be increased to 1000°C or even 2000°C, if the process was rapid enough. If air was first compressed to five atmospheres, then allowed to cool to atmospheric temperature, and finally allowed to expand, it should absorb as much heat as was given out in its compression and its temperature should be lowered by 300°C. From these results he believed that "if we take a mass of compressed air to 50, 100, etc., atmospheres, the cold produced by its instantaneous expansion will have not limit). In other words, it would be possible to achieve unlimited cold by the expansion of gases.Gay-Lussac concluded his paper stating: "If it is undisputable that expansion of a gas can produce an unlimited amount of cold, then the determination of the absolute zero of heat must seem a complete fantasy", agreeing with the general ideas that Lavoisier had expressed earlier.An interesting fact is that Desormes and Clément interpreted Gay-Lussac's results in a completely different manner, arguing that they could actually be used not only to demonstrate the existence of an absolute zero but also to calculate its location. According to Desormes and Clément, to support Gay-Lussac's ideas of unlimited cooling, that is, the temperature could be decreased infinitely, was the same as admitting that the quantity of heat that constitutes this temperature was infinite. If this were the case, then heat would be unlike any other measurable thing or quality.although Desormes and Clément relied on a hypothesis that we know today to be faulty, they were able to arrive by several different methods to a value of the absolute zero quite close to the one accepted today.Comparing the cooling of a body to the flow of caloric and the temperature to the driving force (pressure drop), led to the result that for an elastic fluid the rate flow should be proportional to the active temperature, that is, to the temperature difference. This was exactly what Newton had stated, that the amount of caloric lost was proportional to the temperature difference. Another immediate consequence was that the capacity of dilated air for caloric was the mean between that of air at a high pressure and that of pure space (vacuum)." --JaimeWisniak, "Nicolas Clément" in Educación Química Volume 22, Issue 3, July 2011, Pages 254-266. .

Desormes & Clement's paper: pp. 329-339. First edition of the paper which for the first time explained catalysis - the intermediate compound theory. According to this theory, the desired reaction is brought about by a path involving the formation of an unstable intermediate compound, followed by its decomposition into the desired end products with the regeneration of the catalyst.Parkinson "Breakthroughs", 1806 C.
