Atmospheric pressure atop Mt. Everest is 3.30 × 104 N/m2. (a) What is the partial pressure of oxygen there if it is 20.9% of the air? (b) What percentoxygen should a mountain climber breathe so that its partial pressure is the same as at sea level, where atmospheric pressure is 1.01 × 105 N/m2. (c) One of the most severe problems for those climbing very high mountains is the extreme drying of breathing passages. Why does this drying occur?
