Detailed explanation-1: -Capillary action occurs because water is sticky, thanks to the forces of cohesion (water molecules like to stay close together) and adhesion (water molecules are attracted and stick to other substances).
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: -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.
Detailed explanation-4: -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-5: -Tubes having very small diameters (narrow cylindrical tubes) are called capillary. If these narrow tubes dipped in a liquid it is observed that liquid in the capillary either rises (or) falls relative to the surrounding liquid level. This phenomenon is called capillary action and such tubes are called capillary.
