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 (picture to right) is limited by surface tension and, of course, gravity.

What do you mean by capillarity or capillary action class 11?
Capillarity is an invisible force that works against the force of gravity. It pushes a liquid up in a tube or a narrow pipe. This rising of liquid is the capillary action. We call such liquid capillary water because the water follows the principle of capillarity.
What is capillary action explain with example?
In order for wicking to occur, a tube needs to be sufficiently small in diameter. Examples of capillary action include the uptake of water in paper and plaster (two porous materials), the wicking of paint between the hairs of a paintbrush, and the movement of water through sand.
What is capillary action class 10th?
Capillary action is the resultant of intermolecular attraction between the molecules of water and the adhesive force in between the walls of the capillary and the liquid.
Capillary Action And Why We See A Meniscus | Chemistry | Khan Academy
What is capillary action answer?
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. The surface tension acts to hold the surface intact. Capillary action occurs when the adhesion to the walls is stronger than the cohesive forces between the liquid molecules.
What is capillary action and give an example?
In order for wicking to occur, a tube needs to be sufficiently small in diameter. Examples of capillary action include the uptake of water in paper and plaster (two porous materials), the wicking of paint between the hairs of a paintbrush, and the movement of water through sand.

What is an example of capillary action in plants?
Because water molecules like to stick together (cohesion) and like to stick to the walls of the tubes of cellulose (adhesion), they rise up the tubes all the way from the roots to the leaves. Water then evaporates from the leaves, helping to draw up more water from the roots. This process is called capillary action.
What is capillary action 12th?
Capillary action is the ability of a liquid to flow in narrow spaces without the assistance of, or even in opposition to, external forces like gravity.

What is capillary action class 11?
Capillary action is the ability of a liquid to flow in narrow spaces without the assistance of, or even in opposition to, external forces like gravity.
What is capillary action process?
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 (picture to right) is limited by surface tension and, of course, gravity.
