Explain Dalton's law of partial pressures and Charles’ law.

Explanation

Dalton.s law of partial pressures states that if two or more non-reacting gases are enclosed in a vessel of a definite volume, then at constant temperature, the total pressure exerted by the gas mixture is equal to the sum of partial pressure of individual gases. The individual pressure of the gas is known as partial pressure. So, the total pressure is equal to the sum of partial pressure of each gas. i.e.,
`p_("total")=p_(1)+p_(2)+p_(3) + ............ + p_(n)` (at constant T, V).
Where, `P_("total")` is the total pressure of gaseous mixture and `p_(1),p_(2),p_(3),p_(4),........,p_(n)` are partial pressures of individual gases.
