Clapeyron, Benoit Paul Émile

 

Born Jan. 26, 1799, in Paris; died there Jan. 28, 1864. French physicist. Member of the Paris Academy of Sciences (1858).

Clapeyron graduated from the Ecole Polytechnique in Paris in 1818. From 1820 to 1830 he worked in St. Petersburg at the Institute of Railroad Engineers. Upon returning to France, he became a professor at the School of Bridges and Roads in Paris. In 1834, Clapeyron took note of S. Carnot’s work, retraced his reasoning, and, using the graphic method for the first time in thermodynamics, gave Carnot’s results geometric form. Studying the Carnot cycle, he derived the equation of state of an ideal gas. He also formulated the dependence of the melting and boiling points on temperature.

From a historical perspective, shell theories can be traced back to the 19th century when Clapeyron and Lame [1] formulated the membrane and bending theories of shells.
Despite the heroic advances in thermodynamics not only by Gibbs, but also by the likes of Boltzmann, Clapeyron, Maxwell, and others, the theory of heat transfer and entropy could not be accommodated by the deterministic, time-reversible framework of classical mechanics.
These and other equations devised with the same aim were still reference formulas in 1834, when Clapeyron put them together in his ideal gas law.
The ideal gas law was first stated by Emile Clapeyron in 1834.

Como criterio para determinar si la variabilidad de b con el volumen seria suficiente para encontrar acuerdo entre los resultados de mi formula y los volumenes experimentales del liquido y vapor determinados por Sydney Young, yo use en mi conferencia el principio de Clapeyron el cual, con b variando solo con v y no con T, conduce a la ecuacion
Unos anos despues, en 1834, las ideas de Carnot fueron reelaboradas y expresadas en lenguaje matematico por Emile Clapeyron (1799-1864), pero su trabajo tuvo igualmente poca acogida (Papanelopoulou, 2004: 2).

A commonly known Clapeyron equation defining elasticity potential as the product of components of stress tensor and strain tensor has been applied.
If the Sun was truly a gas, then perhaps some understanding could be harnessed through the ideal gas law, which had been discovered by Clapeyron [28].
