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

  1. A
    Surface tension
  2. B
    Critical phenomenon
  3. C
    Viscosity
  4. D
    Pressure

Solution & Step-by-step Explanation

Surface tension is the property of a liquid surface that causes it to behave like an elastic sheet, acting to minimize its surface area. Since a sphere possesses the minimum surface area for a given volume, cohesive forces pull liquid drops into a spherical shape.
