Question

why do mountainaineers need oxygen cylinders in English​

Answer 1

Explanation:

Atmospheric pressure is low at high altitudes. The volume of air increases and the air becomes less dense because the volume is inversely proportional to density. Hence, a lesser volume of oxygen is available for breathing. Thus, mountaineers have to carry oxygen cylinders with them.

Answer 2

$\large\bold\orange{\underline{Answer:-}}$

➻ Mountaineers carry an oxygen cylinder along with them due to the following reasons :-

• It is because when they climb mountains, as altitude increases, the amount of oxygen level in the atmospheric air decreases as trees are not found at higher altitudes.
• The air pressure gets lower as the altitude increases.
• At the top of the mountain, the air pressure is too low that it is insufficient for oxygen to selectively permeate into the blood...
