a balloon filled with an ideal gas is taken from the surface of the sea deep to a depth of 100m , what will be its volume in terms of its original volume?

Pressure at surface of sea = 760 mm Hg

  = 1033.3 cm H2O

  = 10.3 m H2O

Pressure at 100 m depth = 100 + 10.3 = 110.3 m H2O

Assuming temperature to constant,

P1V1 (at surface) = P2V2 (at 100 m depth)

10.3 x V1 = 110.3 x V2

V2 = 0.093 V1

  = 9.3% of V1.
