Preferred Label : enthalpy of wetting;
IUPAC definition : Referred to unit of mass of the solid, the difference (at constant temperature) between
the enthalpy of a solid completely immersed in a wetting liquid, and that of the solid
and the liquid taken separately. It must be specified whether the solid in the initial
state is in contact with vacuum or with the vapour of the liquid at a given partial
pressure. Measurements of the enthalpy of wetting of a solid equilibrated with varying
relative pressures of the vapour of a pure wetting liquid may be used to derive the
differential enthalpy of adsorption of the vapour.;
