Detailed explanation-1: -The cohesive forces between liquid molecules are responsible for the phenomenon known as surface tension.

Detailed explanation-2: -Cohesion: Hydrogen Bonds Make Water Sticky In the case of water, hydrogen bonds form between neighboring hydrogen and oxygen atoms of adjacent water molecules. The attraction between individual water molecules creates a bond known as a hydrogen bond.

Detailed explanation-3: -Cohesive forces between molecules cause the surface of a liquid to contract to the smallest possible surface area. This general effect is called surface tension.

Detailed explanation-4: -The cohesive and adhesive properties of water allow for another interesting phenomenon: capillary action. If you place a thin straw in a glass of water, the water will be attracted to it. At the same time, however, the water wants to stick together with other water molecules.

Detailed explanation-5: -Hydrogen bonds create the ‘stickiness’ of water, causing the property of cohesion. These bonds are even stronger at the surface of water because there are fewer molecules to bond with, and this creates the surface tension that allows insects to walk on water.
