Force of surface tension predominates the force of gravity

Vedclass · Answer

(B) The shape of a liquid drop is determined by the competition between surface tension forces and gravitational forces.Surface tension acts to minimize the surface area of the liquid,which tends to pull the drop into a spherical shape.Gravitational force acts to deform the drop,pulling it downwards.For small droplets,the surface-to-volume ratio is high,meaning the surface tension force is strong enough to overcome the relatively small gravitational force,keeping the drop spherical.For larger drops,the gravitational force (which depends on mass/volume) increases significantly,eventually dominating the surface tension force and causing the drop to bulge or flatten.

Small droplets of a liquid are usually more spherical in shape than larger drops of the same liquid because
