A big drop of water is sprayed into 1000 small droplets. Find the ratio of surface potential energy of drop to single droplet?

Let,Â

Radius of small droplet be 'r',Â

Radius of big drop be 'R'.Â

Volume of water will remain constant on splitting the drop into droplets.Â

Therefore,Â

R3Â =Â nr3

Here n = 1000,Â

Therefpre, R = 10 r

Now, the surface of the potential energy of drop is,Â

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.

Do intermolecular or inter-atomic forces follow inverse square law?

No. Intermolecular and inter-atomic forces do not obey the inverse square law.
