WebbIn short; surface tension is the property of the liquid in contact with gas phase (usually air). Interfacial 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 ...
