Capillary action is the result of adhesion and surface tension. Adhesion of water to the walls of a vessel will cause an upward force on the liquid at the edges and result in a meniscus which turns upward.

■■ What are the effects of surface tension?

What are the effects of surface tension?Due to the surface tension, small objects will "float" on the surface of a fluid, as long as the object cannot break through and separate the top layer of water molecules. When an object is on the surface of the fluid, the surface under tension will behave like an elastic membrane.

■■What are the application of surface tension?

What are the application of surface tension?Surface tension of soap solution is less, it can spread over large areas and wash clothes more effectively, since the dirt particles stick to the soap molecules. ... Antiseptics like Dettol have low surface tension, so that they spread faster. ● Surface tension prevents water from passing through the pores of an umbrella.
