- Definition: Surface tension is the property of a liquid that allows it to resist an external force, due to the cohesive nature of its molecules. It is the force that acts on the surface of a liquid, making it contract to the smallest possible surface area.
- Formation of Spherical Raindrops: As raindrops fall, surface tension causes the water molecules to be pulled together into a shape with the least surface area for a given volume, which is a sphere. This minimizes the surface area and thus the surface energy of the drop.
- Balance of Forces: While falling, the shape of raindrops can be slightly deformed due to air resistance and other factors, but surface tension continuously acts to maintain the spherical shape as much as possible.
