Dalton's law of partial pressures states that the total pressure of a gas mixture is equal to the sum of the partial pressures of its individual gases.
<h3>What is partial pressure?</h3>
Partial pressure is defined as the pressure exerted by individual gas constituents that makes up a mixture of gases.
According to Dalton's law of partial pressures which states that the total pressure by a mixture of gases is equal to the sum of the partial pressures of each of the constituent gases.
This can be represented mathematically by the following:
P = P1 + P2
Where P = total pressure
P1 = partial pressure of gas 1
P2 = partial pressure of gas 2.

The process by which gasses spontaneously move from an are with higher concentration to one of lower concentration is called diffusion. This process mainly occurs in gases and liquids. The end result of diffusion is called dynamic equilibrium. It is a complete mixing of the molecules of the gas.
