    40 atm

    Explanation:

    Boyle's law states that for a fixed amount of gas the pressure is inversely proportional to the volume of the gas at constant temperature.

    P1V1 = P2V2

    Where P1 is pressure and V1 is volume at the first instance

    And P2 is pressure and V2 is volume at the second instance

    Substituting the values in the equation

    2.0 atm x 200 mL = P2 x 10 mL

    P2 = 40 atm

    The new pressure is 40 atm
