Question

Explain why is human life impossible at higher altitudes with out supplementary supply of oxygen

Answer 1

Answer:

here is ur answer..

ur question depends purely about altitude and temperature...

as we know that as the altitude increases the temperature decreases ..here temperature means mixture of gases...

so oxygen will be less..

even in space we need to carry oxygen cylinder .. beacause of no air...

Answer 2

Oxygen and High Altitudes

To understand why human life is impossible at higher altitudes without supplementary supply of oxygen, we need to first understand how and why oxygen level differs from sea level to higher altitudes.

At sea level, the composition of air remains consistent. When we move towards a certain altitude, the partial pressure of oxygen in the air changes.

What we mean by change in partial pressure is, molecules of oxygen in air starts changing. As we go up, the pressure to push the molecules above decreases which results in less molecules of oxygen at higher altitudes.

At sea level, the partial pressure of oxygen is 160 mmHg (approx.).

At Mt. Everest level, the partial pressure of oxygen reduces to 53 mmHg only.

As we reach at more height, due to less oxygen molecules present, only some of them gets pushed , hence reducing the partial pressure of oxygen.

This is the the reason, at higher altitudes we face difficulty in breathing as less amount of oxygen is present there and hence we need supplementary supply of oxygen to survive.
