Effects and Applications of Surface Tension for Fluidic

• Surface tension is a property of a liquid that allows them to resist external forces. It combines the concepts of cohesion and adhesion. Surface tension is caused by a strong attraction between the molecules (cohesion) that cause them to link together and remain uniform, even when placed on differing surfaces (adhesion). When the molecules possess weak positive interactions, as is the case

surface tension of the milk supports the dye molecules on the surface and keeps the dye relatively centralized. (The tendency to keep a low surface area minimizes the distance that the dye will spread across the milk’s surface.) In contrast, soap is a surfactant. A surfactant(or surface active agent) is a substance that has the ability to reduce the surface tension of a liquid. Therefore
