What Causes Surface Tension?
Intermolecular forces such as Van der Waals's forces cause surface tension to occur. This force draws the liquid particles together. The particles are pulled towards the rest of the liquid along the surface.
Surface tension is can be defined as,
The surface force ( F) ratio to the length (L) along which the force acts.
What is the Unit of Surface Tension?
The SI unit of Surface Tension is measured in Newton per Meter or N/m, and the CGS Unit of Surface Tension is dyn/cm.
