Question

At a constant pressure, the volume of a gas doubles when the temperature in kelvins doubles. This is a statement of which gas law?

Answer 1

Charles' law


Charles law state that at constant pressure, the volume of a certain gas is directly proportional to its temperature

Answer 2

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.

$V\propto T$    (At constant pressure and number of moles)

$\frac{V_1}{T_1}=\frac{V_2}{T_2}$

where,

$V_1$ = initial volume of gas = v

$V_2$ = final volume of gas = ?

$T_1$ = initial temperature of gas = t K

$T_2$ = final temperature of gas = 2t K

Now put all the given values in the above equation, we get the final pressure of gas.

$\frac{v}{t}=\frac{V_2}{2}$

$V_2=2v$

Thus the volume will double when temperature doubles in Kelvin according to Charle's law.
