Surface Tension: Causes, Examples and Dimensions - Collegedunia

WebSurface Tension Cohesive forces between molecules cause the surface of a liquid to contract to the smallest possible surface area. This general effect is called surface tension. Molecules on the surface are pulled inward by cohesive forces, reducing the surface area. WebThe property that allows water molecules to keep climbing higher is COHESION (water molecules sticking together due to hydrogen bonds). This is what makes transpiration in plants possible, and that process involves water moving upwards against gravity from the roots to the leaves. 1 comment ( 8 votes) Upvote Flag Show more...
