The gas in a balloon has P=100000 pa and v=0.0279 m^3. if the pressure increases to 120000 pa at constant temperature, what is the new volume of the balloon? (hint:N and T are constant.) also (Unit=m^3)

    0.02325 m^3

    Explanation:

    P1 = 100000Pa, v1 = 0.0279m^3

    P2 = 120000Pa. V2 = ?

    as mass and temperature are constant using ratio method for Boyle'slaw

    P2V2 = P1V1

    or V2 = P1V1/P2

    V2 = 100000*0.0279/120000

    V2 = 0.02325 m^3
