    Answer:

    (A) three times as large as the initial value.

    Explanation:

    Boyle law states that the pressure is inversely proportional to volume if we kept the temperature constant.

    P_{1} V_{1} = P_{2} V_{2}        (1)

    here P_{1} and V_{1} are the initial pressure and volume.

    P_{2} and V_{2} are the final pressure and volume respectively.

    now

    P_{1} = p\\V_{1} = v\\P_{2} = ?\\V_{2} = \frac{v}{3}

    by putting these values in equation 1.

    hence it is proved that ” if the volume is decreased to one third of its original value then the pressure will be three times larger then its initial value”.
