A scuba diver at 30 meters depth (4 atm total pressure) breathes air with a P_N2 of roughly 3.2 atm.
According to Henry's Law, what happens to the nitrogen in their blood compared to at the surface (1 atm total pressure)?
- The nitrogen forms small bubbles in the blood while the diver is at depth
- The P_N2 in the lungs decreases to match the blood's surface level
- The nitrogen becomes less soluble as the pressure increases
- The concentration of dissolved nitrogen in the blood increases proportionally to the pressure
