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.
