= Saturation pressure
{synonym}
The equilibrium <pressure> of a vapor in contact with its <liquid> or <solid> at a specified <temperature>. For pure <liquid>–<gas> <phase coexistence> with negligible interface effects, it is the <pressure> on their <phase coexistence curve>. In a <gas> <mixture>, distinguish the component's <partial pressure> from the total <pressure>; the pure-substance <Integrated Clausius-Clapeyron relation> does not describe the total <pressure> of arbitrary humid air.
