    Answer:

    ΔV = 0.98 L

    Explanation:

    First, we will calculate the increased volume using Charles’ Law:

    \frac{V_1}{T_1} = \frac{V_2}{T_2}

    where,

    V₁ =initial volume = 18.9 L

    V₂ = final volume = ?

    T₁ = initial temperature = 15°C + 273 = 288 k

    T₂ = final temperature = 30°C + 273 = 303 k

    Therefore,

    \frac{18.9\ L}{288\ k} = \frac{V_2}{303\ k}

    V₂ = 19.88 L

    Now, we calculate the change in volume:

    ΔV = V₂ – V₁ =  19.88L – 18.9 L

    ΔV = 0.98 L

    This is the volume of gasoline that will spill out.
