A drop of mercury of radius 3mm 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 small droplet.

The volume of mercury will remain constant on splitting the drop into droplets.

Therefore,

Why solids have definite shape while liquids do not have definite shape?

Solids: Intermolecular forces are very strong and thermal agitations are not sufficiently strong to separate the molecules from their mean position. Solids are rigid and hence they have definite shapes.
Liquids: In liquids intermolecular forces are not sufficiently strong to hold the molecules at definite sites, as a result they move freely within the bulk of liquid, therefore, do not possess definite shapes. Liquids take the same shape as that of the container.
