    Answer:

    400 kPa

    Explanation:

    The new pressure can be found by using the formula for Boyle’s law which is

    P_1V_1 = P_2V_2

    Since we’re finding the new pressure

    P_2 = \frac{P_1V_1}{V_2} \\

    120 kPa = 120,000 Pa

    We have

    P_2 = \frac{120000 \times 10}{3} = \frac{1200000}{3} \\ = 400000

    We have the final answer as

    400,000 Pa = 400 kPa

    Hope this helps you
