Homework Help: Percentage change in interior volume

  1. Nov 8, 2014 #1
    1. The problem statement, all variables and given/known data

    Deep sea fish experience a tremendous amount of atmospheric pressure.

    When you are at a depth of 2000 m in the sea, the pressure that you will experience is about 200 times atmospheric pressure (1atm=1.0×105N/m2)which you will experience on land.

    If you are lowering a hollow iron spherical shell, imagine a spherical submarine, then by how much does the volume of the interior of this shell change at this depth? Express the ratio in terms of percentange change in interior volume.

    Express your answer to two significant figures and include the appropriate units

    delta V/Vo

    2. Relevant equations

    3. The attempt at a solution
    I know DeltaV/Vo is equal to change in pressure over bulk mod, and change in pressure is 200 atm/Biron. I get 0.02% but that doesn't work.

    Show you calculations. Is the percentage change in volume positive or negative?
