Question

An inflated balloon contains X air molecules.After some time the volume of the balloon is found to be the half at the same temperature and pressure when a few air molecules are expelled out. a)How many molecules will be there in the balloon now? b) Which is the gas law associated with this?

    Answer:

    See explanation

    Explanation:

    According to Avogadro’s law, the volume of a given mass of gas is directly proportional to the number of molecules of gas present at constant temperature and pressure.

    Hence; V1/n1 = V2/n2

    The implication of this is, if there were X molecules present and the volume of the balloon is halved, the number of molecules of gas present is also halved. So, we now have X/2 number of gas molecules present in the balloon.

    This is in accordance with the statement of Avogadro’s law.
