- Surface tension is the tendency of liquid surfaces to shrink into the minimum surface area possible due to cohesive forces between liquid molecules. - For a given volume, a sphere is the shape with the smallest surface area. - Therefore, liquid drops naturally tend to form a spherical shape to minimize their surface energy.
The rain-drops are spherical because
