If a gas has a volume of 750 ml at 25°c, what would the volume of the gas be at 55°c?

Answer : The final volume of gas will be, 681.4 ml

Explanation :

Charles' Law : This law states that volume of gas is directly proportional to the temperature of the gas at constant pressure and number of moles.

    (At constant pressure and number of moles)

or,

where,

= initial volume of gas = 750 ml

= final volume of gas = ?

= initial temperature of gas =

= final temperature of gas =

Now put all the given values in the above formula, we get the final volume of gas.

Therefore, the final volume of gas will be, 681.4 ml
