Detailed explanation-1: -Capillary action (sometimes called capillarity, capillary motion, capillary rise, capillary effect, or wicking) is the process of a liquid flowing in a narrow space without the assistance of, or even in opposition to, any external forces like gravity.

Detailed explanation-2: -Capillary action (or capillarity) describes the ability of a liquid to flow against gravity in a narrow space such as a thin tube.

Detailed explanation-3: -Capillary action can be defined as the ascension of liquids through slim tube, cylinder or permeable substance due to adhesive and cohesive forces interacting between the liquid and the surface.

Detailed explanation-4: -Capillary action is important for moving water (and all of the things that are dissolved in it) around. It is defined as the movement of water within the spaces of a porous material due to the forces of adhesion, cohesion, and surface tension.

Detailed explanation-5: -Capillary action, commonly known as capillary effect or motion, is when liquid flows through narrow spaces without external forces, such as gravity; rather, the liquid’s movement is aided by intermolecular forces present in between the liquid and solid surface(s).
