Answer: Charle's law
Explanation: Charles' Law: This law states that volume is directly proportional to the temperature of the gas at constant pressure and number of moles.
[tex]V\propto T[/tex] (At constant pressure and number of moles)
[tex]\frac{V_1}{T_1}=\frac{V_2}{T_2}[/tex]
where,
[tex]V_1[/tex] = initial volume of gas = v
[tex]V_2[/tex] = final volume of gas = ?
[tex]T_1[/tex] = initial temperature of gas = t K
[tex]T_2[/tex] = final temperature of gas = 2t K
Now put all the given values in the above equation, we get the final pressure of gas.
[tex]\frac{v}{t}=\frac{V_2}{2}[/tex]
[tex]V_2=2v[/tex]
Thus the volume will double when temperature doubles in Kelvin according to Charle's law.
