Detailed explanation-1: -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-2: -Cohesion: Water is attracted to water, and Adhesion: Water is attracted to other substances.

Detailed explanation-3: -Have you ever filled a glass of water to the very top and then slowly added a few more drops? Before it overflows, the water forms a dome-like shape above the rim of the glass. This dome-like shape forms due to the water molecules’ cohesive properties, or their tendency to stick to one another.

Detailed explanation-4: -Cohesion holds hydrogen bonds together to create surface tension on water. Since water is attracted to other molecules, adhesive forces pull the water toward other molecules.

Detailed explanation-5: -Hydrogen bonds cause water to be exceptionally attracted to each other. Therefore, water is very cohesive.
