    V₂ = 97.7 L

    Explanation:

    Given dа ta:

    Initial volume of balloon = 59.5 L

    Initial pressure = 101.3 Kpa

    Final pressure = 61.7 kpa

    Final volume = ?

    Solution:

    Formula:

    P₁V₁ = P₂V₂

    P₁ = Initial pressure

    V₁ = Initial volume

    P₂ = Final pressure

    V₂ = Final volume

    Now we will put the values in formula.

    P₁V₁ = P₂V₂

    101.3 kpa * 59.5 L = 61.7 kpa * V₂

    V₂ = 6027.35 kpa. L / 61.7 kpa

    V₂ = 97.7 L
