Falling drops of water become spheres due to

Explanation:

Surface Tension:

It is defined as force per unit length in the plane of the liquid surface at right angles to either side of an imaginary line drawn to the surface.

• It is the tendency of the liquid surface to shrink into a minimum surface area.
• Mathematically, \(Surface\;Tension = \frac{{Force}}{{Length}}\)
• The SI Unit of surface tension is Nm^-1
• It allows insects to float and slide on the water surface, usually more dense than water

Application of Surface Tension:

• A falling drop of rainwater acquires the spherical shape due to Surface tension.
• This phenomenon can be observed in the nearly spherical shape of small drops of liquids and of soap bubbles.

• Because of this property, certain insects can stand on the surface of the water.
• Raindrops, the rise of sap in a tree, and the break up of liquid jets are examples of surface tension.
