GENERAL KNOWLEDGE

Detailed explanation-1: -Raindrops start to form in a roughly spherical structure due to the surface tension of water. This surface tension is the “skin” of a body of water that makes the molecules stick together. The cause is the weak hydrogen bonds that occur between water molecules.

Detailed explanation-2: -"This remarkable evolution results from a tug-of-war between two forces: the surface tension of the water and the pressure of the air pushing up against the bottom of the drop as it falls. When the drop is small, surface tension wins and pulls the drop into a spherical shape.

Detailed explanation-3: -Because of a phenomenon known as surface tension, water drops, or any other liquid’s drops, are spherical in shape. This acts on the surface of a freely falling drop in a liquid to reduce its area.

Detailed explanation-4: -The cohesive forces between liquid molecules is responsible for the surface tension. The molecules of water on the surface don’t have like molecules around it.So the water droplets tend to be pulled into shape of spherical due to cohesive forces. Thats why, the drop of water is always spherical.
