Question

A SCUBA diver produces a spherical air bubble with bulk modulus B = 1.2 x 10⁵ Pa and radius r1 = 2.9 mm while exploring a shipwreck below the surface of the ocean. The air bubble rises to the surface of the ocean and expands to a radius r2  = 3.8 mm. What is the difference in pressure between the surface and at the SCUBA diver's depth,

( Psurface − P diver )?

Answer 1

Then , V1 = 4/3 pi r1^3

V2 = 4/3 pi r2^3
