    To solve this, you need to use a relationship for gases known as Charles' Law. Charles' Law says that at a constant pressure, volume and temperature have a direct proportionality relationship. The equation accompanying this is:

    (V1) / (T1) = (V2) / (T2)

    We have 3 known values so we can solve for the fourth:

    V1 = 43.4 L

    T1 = 305 K

    T2 = 273 K

    V2 = Unknown

    Plugging into our equation:

    (43.4 L) / (305 K) = (V2) / (273 K)

    V2 = (43.4 L/305K) * (273 K)

    V2 = 38.8 L = Volume the balloon occupies at 273 K

    This makes sense, as a hotter gas will have more average kinetic energy, and would take up a large volume. When the volume was calculated at a lower temperature, the calculated volume decreased as expected.
