Clausius–Clapeyron-ekvationen är en ekvation inom termodynamiken som beskriver sambandet mellan tryck och temperatur vid en fasövergång, exempelvis hur kokpunkten för en vätska ändras som funktion av trycket. This behavior can be explained with the Clausius-Clapeyron equation.

2019-05-05 · The Clausius-Clapeyron equation approximately relates a substance’s vapor pressure and its temperature. (The exact relationship is called the Clapeyron equation. A derivation of the Clausius-Clapeyron equation can be found in Section 4.5 of Atkins, Physical Chemistry 9th Ed.) En chimie physique, et plus particulièrement en thermodynamique, la formule de Clausius-Clapeyron (ou relation de Clausius-Clapeyron, équation de Clausius-Clapeyron) est une forme simplifiée de la formule de Clapeyron permettant son intégration dans le cas d'un équilibre liquide-vapeur d'un corps pur. Clausius-Clapeyron Equation It is possible to characterize the phase-equilibrium line in terms of a differential equation. Referring to Figure 9.1, consider a point, such as , that lies on the phase-equilibrium line, and corresponds to the temperature and the pressure . The condition implies that The Clausius-Clapeyron equation relates the latent heat (heat of transformation) of vaporization or condensation to the rate of change of vapour pressure with temperature.

The condition implies that The Clausius-Clapeyron relationship is the rate of increase of saturated vapour pressure with temperature and is important in regulating many of the processes of the hydrological cycle. For example, as the temperature of the atmosphere increases its water holding capacity also increases according to the Clausius-Clapeyron relationship. The Clausius–Clapeyron equation determines the vapor pressure of a liquid as a function of temperature (in degrees K). In differential form, the CC equation can be written , where is the standard molar enthalpy of vaporization.

T at equilibrium: dµi(α,P',T') = dµi(β,P',T'). In meteorology, a specific derivation of the Clausius-Clapeyron equation is used to describe dependence of saturated pressure on temperature.
