Question

3. If a certain quantity of gas has a volume of 30 cm3 at a pressure of 1 × 105 Pa, what is its volume when the pressure is
a. 2 × 105 Pa,
b. 5 × 105 Pa?
Assume the temperature remains constant.

    We know that:

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

    Given at P_{1}=30cm^3 , V_{1}=10^5Pa

    a)

    When P_{2}=2*10^5Pa , V_2=?

    Using equation (1)

                                        30*10^5=2*10^5*V_2

                                         V_2=30/2=15cm^3

    b)

    When P_2=5*10^5Pa, V_2=?

    using equation (1)

                                         30*10^5=5*10^5*V_2

                                        V_2=30/5=6cm^3
