Surface Tension and Capillary Action - Edinformatics

Web• 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 ... WebThe model of a liquid surface acting like a stretched elastic sheet can effectively explain surface tension effects. For example, some insects can walk on water (as opposed to floating in it) as we would walk on a trampoline—they dent the surface as shown in Figure 11.25(a). Figure 11.25(b) shows another example, where a needle rests on a water surface.
