A. The partial pressure of oxygen in atmospheric air at sea level is greater than the partial pressure of oxygen in atmospheric air at the top of Mt. Everest.
What is partial pressure?
Partial pressure is the pressure exerted by a component of mixture of gases.
Partial pressure of oxygen in different location of the Earth
The depth (distance from top to bottom) of the atmosphere is greatest at sea level and decreases at higher altitudes.
With greater depth of the atmosphere, more air is pressing down from above.
Air pressure is greatest at sea level and falls with increasing altitude.
Thus, the partial pressure of oxygen in atmospheric air at sea level is greater than the partial pressure of oxygen in atmospheric air at the top of Mt. Everest.
