WebInterfacial tension, on the other hand, is the property between any two substances. It could be liquid-liquid, liquid-solid or solid-air. Surface and interfacial tension are usually presented by the symbol σ and it is measured by force per unit length. WebThe origins of interfacial tension are analogous. Interfacial tension is a material property of a ﬂuid-ﬂuid interface whose origins lie in the diﬀerent attractive intermolecular forces that act in the two ﬂuid phases. The result is an interfacial energy per area that acts to resist the creation of new interface, and that is equivalent ...
