Abstract
BECAUSE of frequent misunderstandings, we would like to emphasize that the work of adhesion w SL in the equation, which one of us has recently pleaded1 should be called Young's equation, is the reversible work required, per square centimetre, to separate the liquid from the solid, leaving an adsorbed film in equilibrium with the saturated vapour of the liquid on the surface of the solid. This work is less than the work W SLO required to separate the liquid from the solid, leaving a clean surface free from adsorbed vapour, by ΠSV°, the surface pressure of the adsorbed film of vapour on the solid. Calling W SL in (1), W SLV°, to indicate the presence of the adsorbed film of saturated vapour,
