Capillary attraction
WebWe can define capillary action as a phenomenon where ascension of liquids through a tube or cylinder takes place. This primarily occurs due to adhesive and cohesive forces. The liquid is drawn upward due to this interaction between the phenomena. Narrower the tube, higher will the liquid rise. WebThese molecules, in turn, attract those around them. ( capillary action )The chain continues to the ground and moves water from the roots to the tree top just as a pump brings water to the surface from a well. Click here to …

Webcapillary attraction n. The force that results from greater adhesion of a liquid to a solid surface than internal cohesion of the liquid itself and that causes the liquid to be raised against a vertical surface, as water is in a clean glass tube.
