GENERAL KNOWLEDGE

Detailed explanation-1: -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.

Detailed explanation-2: -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-3: -Bubbles are spherical because there is an attractive force called surface tension that pulls molecules of water into the tightest possible groupings. And the tightest possible grouping that any collection of particles can achieve is to pack together into a sphere.
