"WebCAPILLARY ACTION The tendency of a fluid to be raised or suppressed in a narrow tube, or capillary tube, is called capillary action. If a capillary tube is placed vertically into a liquid, as shown in Figure 8, capillary action will raise or suppress the liquid inside the tube depending on the combination of substances.

WebDec 6, 2013 · The surface tension force pulls the liquid tangential to the wall of the capillary. When a capillary is dipped in water, it starts rising up due to pulling force from the solid-vapor interface. If the capillary has insufficient length, as the water rises it accelerates till the end of the capillary. WebCapillary action is the net result of two opposing sets of forces: cohesive forces, which are the intermolecular forces that hold a liquid together, and adhesive forces, which are the attractive forces between a liquid and the substance that composes the capillary. Cohesive forces bind molecules of the same type together
