PREMIERE RELATION DE CLAPEYRON

Informations contenues dans le diagramme de phase. Substituting into the Clapeyron equation. Un peu d histoire Lien entre diagramme de Clapeyron et diagramme de phase. For transitions between a gas and a condensed phase with the approximations described above, the expression may be rewritten as. These last equations are useful because they relate equilibrium or saturation vapor pressure and temperature to the latent heat of the phase change, without requiring specific volume data. One may therefore use the Gibbs—Duhem relation.

On a pressure — temperature P—T diagram, the line separating the two phases is known as the coexistence curve. The Clausius—Clapeyron relation gives the slope of the tangents to this curve. The second derivative of the coexistence curve of phases 1 and 2 is given by [12]. On y distingue les deux temps:

Valeurs extraites de thermexcel. The Clausius—Clapeyron relation characterizes behavior of a closed system during a phase changeduring which temperature and pressure are constant by definition. Imaginons que vous exposiez. Lien entre diagramme de Clapeyron et diagramme de phase. La constante des gaz parfaits est: These last clapeyrln are useful because they relate equilibrium or saturation vapor pressure and temperature to the latent heat of the phase change, without requiring specific volume data.

Schwartzentruber, Les Bases de la Thermodynamique: Retrieved from ” https: Given that a phase change is an internally reversible processand that our system is closed, the first law of thermodynamics holds.

If the latent heat is known, then knowledge of one point on the coexistence curve determines the rest of the curve.

While the Clausius—Clapeyron relation gives the slope of the coexistence curve, it does not provide any information about its curvature or second derivative.
