A high-altitude balloon contains 97.5 L of helium gas at 95.8 kPa. What is the volume when the balloon rises to an altitude where the pressure is only 21.5 kPa? (Assume that the temperature remains constant.)

  • chemistry -

    P*V = constant at constant T.

    It's somebody's Law. Boyle's?

    P1*V1 = P2*V2

    You aleady know P1, P2 and V1.

    Solve for V2.

    no its Charles' Law
