Detailed explanation-1: -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.

Detailed explanation-2: -A wet fluid displays such type of capillary action that is further caused due to the forces of cohesion and surface tension acting together. 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.

Detailed explanation-3: -Capillary action is caused by the combination of cohesive forces of the liquid and the adhesive forces between the liquid and tube material. Cohesion and adhesion are two types of intermolecular forces.

Detailed explanation-4: -Capillary action depends on cohesion, the attraction between particles of the same substance, and adhesion, the attraction between particles of different substances. When adhesion is strong enough, it will overpower cohesion between water molecules, and water will move up a surface or through a surface.

Detailed explanation-5: -How do we define the surface tension of a liquid through the capillary rise method? When a liquid rises in a capillary tube, the weight of the column of the liquid of density inside the tube is supported by the upward force of surface tension acting around the circumference of the points of contact.
