How does the surface tension help in skating?

We know that, with increase of pressure, melting point of ice decreases. Under the skater, ice melts and small tiny water droplets are formed. Due to the small size of water droplets, the excess pressure inside the droplets is sufficiently high and the drops remain spherical in shape. Thus, under the pressure of the skater, drops remain spherical in shape and acts as a ball bearing. Hence, the skater rolls over the drops.

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.

What is hydrostatics?

Hydrostatics is the branch of fluid mechanics that studies incompressible fluids at rest. The study of fluids at rest or objects placed at rest in fluids is hydrostatics.
