How does cohesion cause surface tension
WebMar 23, 2024 · Surface energy = Surface tension × Change in the surface area. or. ES = T × ΔA. where T denotes surface tension and ΔA denotes an increase in surface area. Therefore, the SI unit of surface energy is Nm -2 and the dimensional formula is [MT – 2 ]. 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. WebWe would like to show you a description here but the site won’t allow us.
