Torricelli’s barometer used mercury. Pascal duplicated it using French wine of density 984 kg/m3. Determine the height of wine column for normal atmospheric pressure.

Density of wine = 984 kg/m3

Now, according to Pascal's law, we have

Pressure due to height column of liquid is,

... (1)

The normal atmospheric pressure is 760 mm og Hg.

If h' is the height column of wine corresponding to one atmospheric pressure, then

... (2)

where $\mathrm{\sigma }$ is the density of the wire.

Now from equations (1) ad (2), we get

,

is the height of wine column for normal atmospheric pressure.

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

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

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.
