  1. The vapor pressure of a system, at a given temperature, for which the vapor of a substance is in equilibrium with a plane surface of that substance's pure liquid or solid phase; that is, the vapor pressure of a system that has attained saturation but not supersaturation.
    The saturation vapor pressure of any pure substance, with respect to a specified parent phase, is an intrinsic property of that substance and is a function of temperature alone. For water vapor, the saturation pressure over supercooled liquid differs appreciably from that over ice.
    Compare equilibrium vapor pressure, vapor tension;
    see Clapeyron-clausius equation.
  2. Same as equilibrium vapor pressure.

presión de saturación del vapor[edit | edit source]

  1. Es la presión de vapor de un sistema a una temperatura dada en la que el vapor de una sustancia se encuentra en equilibrio con el plano de la superficie de la fase líquida o sólida pura de dicha sustancia; es decir, es la presión de vapor de un sistema que ha alcanzado la saturación, aunque no la sobresaturación.
  1. La presión de saturación del vapor de cualquier sustancia pura, con respecto a la fase matriz especificada, es una propiedad intrínseca de dicha sustancia y es función de únicamente la temperatura. Para el vapor de agua, la presión de saturación sobre el líquido superenfriado difiere de manera apreciable de la presión sobre hielo.
    Compare presión de vapor en equilibrio, tensión del vapor;
    consulte ecuación Clapeyron-Clausius.
  1. es lo mismo que presión del vapor en equilibrio.
