Asolid gold bar is pulled up from the hold of the sunken rmstitanic.
(a)what happens to its volume as it goes from the pressure atthe ship to the lower pressure at the ocean's pressure?
(b) the pressure difference is proportional to the depth. howmany times greater would the volume change have been had the shipbeen twice as deep?
(c) the bulk modulus of lead is one-fourth that of gold. findthe ratio of the volume change of a solid lead bar to that of agold bar of equal volume for the same pressure change.
