equation de Clausius Claperyon

Chimie; Chimie générale

The Clausius-Clapeyron equation predicts the temperature dependence of vapor pressures of pure liquids or solids.

temperature de Curie

Chimie; Chimie générale

Temperature above which a ferromagnetic material loses its ferromagnetism.

The total pressure exerted by a mixture of gases is the sum of the pressures that each gas would exert if it were alone. For example, if dry oxygen gas at 713 torr is saturated with water vapor at 25 ...

debye

Chimie; Chimie générale

A common non-SI unit of dipole moment , named for Dutch physical chemist Peter Debye. A charge separation equal to one electron charge placed one Ångstrom unit apart has a dipole moment of 4.8 D. ...

Fahrenheit

Chimie; Chimie générale

A temperature scale proposed by Daniel Gabriel Fahrenheit (1686-1736) which uses the melting point of ice (32°F) and the boiling point of water at one atmosphere (212°F) as calibration points. ...

energie libre de formation de Gibbs

Chimie; Chimie générale

The change in Gibbs free energy that accompanies the formation of one mole of a compound from its elements in their most stable form.

energie libre de Helmholtz

Chimie; Chimie générale

A thermodynamic property that can be used to predict whether a process will occur spontaneously at constant volume and temperature. Helmholtz free energy A is defined as A = U - TS where U, T and S ...
