  skos:definition "La pression de vapeur est la pression partielle de la vapeur d'un corps présent également sous forme liquide ou solide. Lorsque le système est à l'équilibre (les proportions relatives de gaz et liquide ou solide ne varient pas), la pression de vapeur est dite « saturante ». Lorsque le système est hors équilibre : si la pression de vapeur est inférieure à la pression de vapeur saturante, une portion de liquide ou de solide passe sous forme gazeuse (évaporation, vaporisation ou sublimation) ; si la pression de vapeur est supérieure à la pression de vapeur saturante, une portion de la vapeur passe sous forme liquide ou solide (liquéfaction, condensation). (Adapté de : <a href=\"https://fr.wikipedia.org/wiki/Pression_de_vapeur\">https://fr.wikipedia.org/wiki/Pression_de_vapeur</a>)"@fr, "Vapor pressure or equilibrium vapor pressure is the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases (solid or liquid) at a given temperature in a closed system. The equilibrium vapor pressure is an indication of a liquid's thermodynamic tendency to evaporate. It relates to the balance of particles escaping from the liquid (or solid) in equilibrium with those in a coexisting vapor phase. A substance with a high vapor pressure at normal temperatures is often referred to as volatile. The pressure exhibited by vapor present above a liquid surface is known as vapor pressure. As the temperature of a liquid increases, the attractive interactions between liquid molecules become less significant in comparison to the entropy of those molecules in the gas phase, increasing the vapor pressure. Thus, liquids with strong intermolecular interactions are likely to have smaller vapor pressures, with the reverse true for weaker interactions.
