Question

Falling raindrops are spherical because:
  1. A
    Air resistance forces sphere shape
  2. B
    Surface tension minimises surface area for given volume
    Correct
  3. C
    Water has uniform density
  4. D
    Clouds are round

Correct answer

Surface tension minimises surface area for given volume

Explanation

For a given volume, sphere has minimum surface area. Surface tension minimises surface energy → spherical shape.
