Capillary action is caused by the combination of cohesive forces of the liquid and the adhesive forces between the liquid and tube material.
Capillary action is caused by the combination of cohesive forces of the liquid and the adhesive forces between the liquid and tube material.
The correct option is A True
Capillary action describes the spontaneous flow of a liquid into a narrow tube or porous material. This movement does not require the force of gravity to occur. 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. The pulling up of liquid occurs when the adhesion to the walls is stronger than the cohesive forces between the liquid molecules and the pull-down of liquid occurs when the adhesion to the walls is weaker than the cohesive forces between the liquid molecules.
