Referred to unit of mass of the solid, the difference (at constant temperature) between the @[email protected] of a solid completely immersed in a @[email protected] 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 @[email protected] Measurements of the @[email protected] of @[email protected] of a solid equilibrated with varying relative pressures of the vapour of a pure @[email protected] liquid may be used to derive the differential @[email protected] of adsorption of the vapour.
