A drop of mercury of radius 3 mm splits into 27 identical droplets. Find the increase in surface energy. Surface tension of mercury is 0.465 N/m.

Let r be the radius of the small droplet. As the volume of mercury will remain constant on splitting the drop into droplets, therefore

- When a sewing needle is gently placed on the surface of water, it floats. Why?
- Define surface energy and show that surface energy is equal to surface tension.
- n identical drops (each of radius r) of liquid of surface tension T and density coalesce to form single drop. The energy released in the processes is converted into kinetic energy. Find the speed of drop.
