Let us assume that a seal's lungs makes up 10% of its bodies volume when full, and that the average density of a seal is 980 kg/m3 when its lungs are full. If the air in the seal's lungs obeys Boyle's law, at what depth would this seal achieve neutral buoyancy in sea water, which has a density of 1020 kg/m3? Assume there are no changes to other tissues in the seal as it dives and that atmospheric pressure is about 1x105 Pa. Before diving, seals may exhale to reduce the amount of air in their lungs. This would increase their density (decreasing their overall volume), and, therefore, reduce their buoyancy so that it is easier for them to dive.]
A. 6.5 m
B.16.5 m
C165 m
D.1.65 m
