Surface tension of liquid lead

Vedclass · Answer

(D) The correct answer is $(d)$.In the manufacturing process of lead shots,molten lead is poured from a height through a sieve. As the liquid lead falls,it forms droplets. Due to the property of surface tension,the free surface of a liquid drop always tends to minimize its surface area for a given volume. Since a sphere has the minimum surface area for a given volume,the falling droplets naturally take on a spherical shape before solidifying,resulting in spherical lead shots.

The property utilized in the manufacture of lead shots is ...............
