Capillary action occurs when the adhesion to the walls is stronger than the cohesive forces between the liquid molecules. The height to which capillary action will take water in a uniform circular tube is limited by surface tension and, of course, gravity.
capillary tube is a simple tube made up of thin and rigid material ,
and also , you can define capillary action as -ability of a liquid to flow in narrow spaces without the assistance of, or even in opposition to, external forces like gravity.
