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 occurs when intermolecular adhesive forces between a liquid and another substance are stronger than the cohesive forces between liquid molecules. Water is adhesive to the glass capillary tubes due to hydrogen bonding.
Detailed explanation-3: -Cohesion: Hydrogen Bonds Make Water Sticky Water has an amazing ability to adhere (stick) to itself and to other substances. The property of cohesion describes the ability of water molecules to be attracted to other water molecules, which allows water to be a “sticky” liquid.
Detailed explanation-4: -Hydrogen bonds cause water to be exceptionally attracted to each other. Therefore, water is very cohesive.
Detailed explanation-5: -This upward motion against gravity, known as capillary action, depends on the attraction between water molecules and the glass walls of the tube (adhesion), as well as on interactions between water molecules (cohesion).
