Detailed explanation-1: -Water likes to stick to itself, but under certain circumstances, it actually prefers to stick to other types of molecules. 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: -Two examples of adhesion are: water droplets sticking to a window after a rainfall, and dew drops hanging from the leaves of a plant.

Detailed explanation-3: -Adhesion is an attraction between molecules of different substances, like how water sticks within the material of a napkin. When molecules of the same substance are attracted to each other they exhibit cohesion. For example, when water molecules stick to each other forming droplets.

Detailed explanation-4: -Water Experiments in Space Water is very adhesive; it sticks well to a variety of different substances. Water sticks to other things for the same reason it sticks to itself – because it is polar so it is attracted to substances that have charges.
