    If the volume of a cylinder is reduced from 8 L to 4 L the pressure of the gas in the cylinder will change from 70 kilopascals to 140 KPa.

    Explanation:

    Given dа ta:

    Initial volume = 8 L

    Final volume = 4 L

    Initial pressure = 70 KPa

    Final pressure = ?

    Solution:

    According to Boyles law:

    P₁V₁ = P₂V₂

    P₂ = P₁V₁ / V₂

    P₂ = 70 KPa * 8 L / 4 L

    P₂ = 560 KPa. L/4 L

    P₂ = 140 KPa

    If the volume of a cylinder is reduced from 8 L to 4 L the pressure of the gas in the cylinder will change from 70 kilopascals to 140 KPa.
