If deep-sea divers rise to the surface too quickly, nitrogen bubbles in their blood can expand and prove fatal. This phenomenon is known as the bends. If a scuba diver rises quickly from a depth of 25 m in Lake Michigan (which is fresh water), what will be the volume at the surface of an N2 bubble that occupied 1.0 mm3 in his blood at the lower depth? Does it seem that this difference is large enough to be a problem? (Assume that the pressure difference is due to only the changing water pressure, not to any temperature difference. This assumption is reasonable, since we are warm-blooded creatures.)

Question
If deep-sea divers rise to the surface
too quickly, nitrogen bubbles in their blood can expand and prove fatal.
This phenomenon is known as the bends. If a scuba diver rises quickly
from a depth of 25 m in Lake Michigan (which is fresh water), what
will be the volume at the surface of an N2 bubble that occupied 1.0 mm3
in his blood at the lower depth? Does it seem that this difference is large
enough to be a problem? (Assume that the pressure difference is due
to only the changing water pressure, not to any temperature difference.
This assumption is reasonable, since we are warm-blooded creatures.)
