Question

Rain drops take up spherical shape naturally due to the ____________ of water.​

Answer 1

Answer:

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.

Answer 2

Rain drops take up spherical shape naturally due to the SURFACE TENSION of water.

• Surface Tension is the inherent property of the surface of a liquid by the virtue of which it resists any external force.

• Surface tension mainly occurs due to the cohesive forces between the liquid molecules.

• The surface molecules of water experience cohesive attraction towards the bulk of the liquid. Since sphere has a very less amount of surface : volume ratio, the falling raindrops/waterdrops always form a spherical shape.
