A solid gold bar is pulled up from the hold of the sunken RMS Titanic.
(a) What happens to its volume as it goes from the pressure at the ship to the lower pressure at the ocean's surface?
(b) The pressure difference is proportional to the depth. How many times greater would the volume change have been had the ship been twice as deep?
(c) The bulk modulus of lead is one-fourth that of gold. Find the ratio of the volume change of a solid lead bar to that of a gold bar of equal volume for the same pressure change.
