Deduce Charle's kaw from kinetic gas equation.

Explanation

Charles' law : According to kinetic theory, the average of K.E of gas molecules is directly proportional to the absolute temperature.
(i.e.,) `K.E prop T`. But `K.E=1/2 mnc^2`
`therefore 1/2 mnc^2 prop T (or) 1/2 mnc^2=KT`
According to kinetic gas equation
(or) `PV=2/3 times 1/2 mnc^2 (or) PV=2/3 times KT`
(or) `V=2/3 (KT)/P`
IF 'P' is kept constant , then V
=constant `times` T(or) `times` T(P constant)
At constant pressure, the volume of a given mass of gas is directly proportional to its absolute temperature. This is Charle's law.
