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: -Water molecules are bent so the hydrogen atoms are to one side of the oxygen atom. and when it come to molecules opposites attract. A bond forms between the negative side of one water molecule and the positive side of another. At that is what gives water its stickiness.
Detailed explanation-3: -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-4: -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-5: -Answer and Explanation: Adhesion is created when water hydrogen bonds with other molecules, allowing water to creep or climb up surfaces.
