An arctic weather balloon is filled with 22.6l of helium gas inside a prep shed. the temperature inside the shed is 7°c. the balloon is then taken outside, where the temperature is 5°c. calculate the new volume of the balloon.?

Answer : The new volume of the balloon is, 22.4 L

Explanation :

Charles' Law : It is defined as the volume of gas is directly proportional to the temperature of the gas at constant pressure and number of moles.

or,

where,

= initial volume of gas = 22.6 L

= 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 the gas.

Therefore, the new volume of the balloon is, 22.4 L
