In SCUBA diving, breathing gas, a mixture of oxygen and other gases, is carried in a breathing tank on the diver's back. This gas must be pressurized so the diver can breath underwater; it is not sufficient to simply bring unpressurized breathing gas or normal air underwater. Based on the Fick diffusion equation, what can you conclude about the concentration of oxygen available to the diver underwater?
A. The atmospheric and water pressure increases the amount of oxygen that can be extracted from unpressurized breathing gas. B. The concentration of oxygen is lower in breathing gas than in normal air. C. The atmospheric and water pressure decreases the amount of oxygen that can be extracted from unpressurized breathing gas. D. The atmospheric and water pressure does not affect the amount of oxygen that can be extracted from unpressurized breathing gas.
