Change in volume: scuba diving
When scuba diving, it is important to come back to the surface of the water from deep dives slowly. If this does not happen, then the diver can get the ?bends?. Determine the amounts of N2 and O2 dissolved in 7.5 L of blood at 298 K at a depth of 100.0 feet below the surface of the water. What is the total volume of dissolved air at this depth? If the diver were to suddenly return to the surface, what would the volumes of N2 and O2 dissolved in their blood be (assume no loss of gas molecules from the system)? What is the change in the volume of dissolved gases in going from 100.0 feet to the surface (instantaneously)? (This is what is responsible for getting the ?bends?.) (33ft of sea water equates to 1 atm increased pressure.)
