Detailed explanation-1: -Adhesion is the attraction of molecules of one kind for molecules of a different kind, and it can be quite strong for water, especially with other molecules bearing positive or negative charges.

Detailed explanation-2: -Cohesion: Hydrogen Bonds Make Water Sticky 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-3: -Capillary action occurs because water molecules bond each other strongly due to forces of cohesion and adhesion where water molecules are attracted and stick to other substances such as glass or paper. Adhesion of water to the surface of a material will cause an upward force on the liquid.

Detailed explanation-4: -Cohesion. Molecules of pure substances are attracted to themselves. This sticking together of like substances is called cohesion. Depending on how attracted molecules of the same substance are to one another, the substance will be more or less cohesive.

Detailed explanation-5: -This is called adhesion because the attraction is to a different substance. In all systems within which water interacts with another surface, both adhesion and cohesion are factors.
