Capillary phenomenon คือ
WebCapillary rise or capillarity is a phenomenon in which liquid spontaneously rises or falls in a narrow space such as a thin tube or in the voids of a porous material. Surface tension is an important factor in the phenomenon of capillarity. The surface adhesion forces or internal cohesion present at the interface between a liquid and a solid stretch the liquid … WebCapillary Action. Tubes having very small diameters (narrow cylindrical tubes) are called capillary. If these narrow tubes dipped in a liquid it is observed that liquid in the capillary either rises (or) falls relative to the surrounding liquid level. This phenomenon is called capillary action and such tubes are called capillary.

WebJan 9, 2024 · Capillary action is defined as the spontaneous flow of a liquid into a narrow tube or porous material. This movement does not require the force of gravity to occur. In fact, it often acts in opposition to gravity. Capillary action is sometimes called capillary motion, capillarity, or wicking. Capillary action is caused by the combination of ...
