Surface Tension Surface tension is the skin-like surface of a liquid due to the cohesive forces between the liquid molecules. The diagram below shows an imagined magnified view of the surface of water, the molecules of liquid at the surface do not have other like- molecules above them.
Surface Tension vs Interfacial Tension. Both surface tension and interfacial tension are effects based on liquids. Both these effects take place due to the unbalanced intermolecular forces between the liquid or solutions molecules.
