The spherical shape of water drops
- Surface tension is a property for liquids and arises from intermolecular forces of attraction.
- One can notice that a molecule in the interior of the liquid is attracted equally from all directions by the molecules around it.
- While a molecule at the surface of the liquid is attracted only sideways and toward the interior.
- The forces on the sides being counterbalanced the surface molecule are pulled only inward the liquid.
- The surface of the liquid is under tension and to have the minimum number of molecules at the surface of the liquid that contracts to have the smallest possible area.
- Surface tension is the unbalanced surface force
This is the reason behind the spherical shape of the raindrop. All liquids have surface tension but for water, it's higher than most.
Raindrops are spherical in shape. This is due to Surface Tension.
