Answer
- A The total pressure of a gas mixture is the sum of the partial pressures of its gases
Explanation
According to Dalton's law, the total pressure is made up of the partial pressures of the individual gases. Because the proportion of oxygen stays at about 21 %, its partial pressure falls with the air pressure. This explains altitude hypoxia, not a lower proportion of oxygen.
