Law of atmosphere states that,

According to Archimedes principle, we have,

Apparent weight Weight of the water displaced – weight of the suspended particle

is the Density of the water

is the Density of the suspended particle

is the Mass of the suspended particle

is the Mass of the water displaced

is the Volume of a suspended particle

Boltzmann’s constant

Substituting equation (2) and equation (3) in equation (1), we get,
