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)

`(V_1)/(T_1)=(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.

`(v)/(t)=(V_2)/(2)`

`V_2=2v`

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