To what temperature must a balloon, initially at 25°c and 2.00 l, be heated in order to have a volume of 6.00 l?

894 K

Solution :

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

    (At constant pressure and number of moles)

The combined gas equation is,

where,

= initial volume of gas = 2.00 L

= final volume of gas = 6.00 L

= initial temperature of gas =

= final temperature of gas = ?

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

Therefore, the temperature must be 894 K in order for balloon to have a volume of 6.00 L.
