What is surface tension?

Water has surface tension. Water has high cohesive and adhesive. The polarity of water causes it to be cohesive and adhesive.

What is cohesion?
Cohesion is the action of like molecules sticking together to water molecules, being mutually attractive by hydrogen bond. Molecules liquid state experience strong intermolecular attractive forces. For example, the molecules of a water droplet are held together by cohesive forces, and the especially strong cohesive forces at the surface constitute surface tension


What is adhesion?

Adhesion is the action of water molecules stick or cling together to other polar molecules by hydrogen bonding.The adhesive forces between water molecules and the walls of a glass tube are stronger than the cohesive forces lead to an upward turning meniscus at the walls of the vessel and contribute to capillary action
