Which of the following property of water can be used to explain the spherical shape of rain droplets ?

Options

A. Viscosity
B. Surface tension
C. Critical phenomena
D. Pressure

Answer

B

Explanation

The spherical shape of rain droplets is due to surface tension. The lowest energy state of a liquid will be when the surface area is minimum. Surface tension tries to decreases the surface area of the liquid to the minimum. The rain droplets are spherical because for a given volume, a sphere has minimum surface area.
