State and explain Charle's law.

Explanation

Charles. law : At constant pressure, the volume of a given mass of gas is directly proportional to absolute temperature.
`V = KT `
`(V )/(T ) =K`
Where V is the volume and T is the absolute temperature. `V_1 and V_2` are the initial and final volumes of a given mass of the gas at the absolute temperatures `T_1 and T_2` respectively at constant pressure.
` (V_1)/(T_1) = k , (V_2)/( T_2) =k`
` or (V_1)/(T_1) = (V_2)/(T_2) =k`
