    V₂ = 1.5 L

    Explanation:

    Given dа ta:

    Initial volume of balloon = 1.76 L

    Initial temperature = 295 K

    Final temperature = 253.15 K

    Final volume = ?

    Solution:

    According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.

    Mathematical expression:

    V₁/T₁ = V₂/T₂

    V₁ = Initial volume

    T₁ = Initial temperature

    V₂ = Final volume

    T₂ = Final temperature

    Now we will put the values in formula.

    V₁/T₁ = V₂/T₂

    V₂ = V₁T₂/T₁

    V₂ = 1.76 L * 253.15 K / 295 K

    V₂ = 445.54 L. K / 295 K

    V₂ = 1.5 L
