Surface tension explains the property of the liquid surface which enables it to resist external forces. Hence :
- Surface tension causes water to resist external forces on surface like glass.
- Water molecules are attracted to other water by a process called cohesion.
- Surfactants are used to break cohesion between water molecules, making surfaces wetter and allowing water to wash away dirt.
The resistive force of adhesion between glass surfaces and water causes water to spread out on such surfaces.
Water to water molecules exhibit cohesive force of attraction
Surfactants such as soap or wetting agents are used to reduce surface tension, hence breaking the cohesive force between water molecules.
