Definition: at a point of a line on the interface of two fluids or a fluid and a solid, quantity equal to the derivative of the component F of the force, tangent to the surface and perpendicular to the line, with respect to curvilinear abscissa l, thus γ=dF/dl MathType@MTEF@5@5@+= feaagKart1ev2aqatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbbjxAHX garuavP1wzZbItLDhis9wBH5garmWu51MyVXgarqqtubsr4rNCHbGe aGqk0di9Wr=fpeei0di9v8qiW7rqqrVepeea0xe9LqFf0xc9q8qqaq Fn0lXdHiVcFbIOFHK8Feea0dXdar=Jb9hs0dXdHuk9fr=xfr=xfrpe WZqaaeaaciWacmGadaGadeaabaGaaqaaaOqaaiabeo7aNjabg2da9K qzafGaaeizaOGaamOraiaac+cajugqbiaabsgacaWGSbaaaa@411F@

NOTE 1 The surface tension is equal to the work ΔW needed to expand the surface by an area ΔA, divided by ΔA, thus γ = ΔW / ΔA.

NOTE 2 The coherent SI unit of surface tension is newton per metre, N/m or, equally, joule per square meter, J/m2.
