USES OF OXYGEN

USES OF OXYGEN.
Oxygen is put in cylinders for use where natural supply is not sufficiently enough. This is mainly in:

(i) Mountain climbing/Mountaineering-at high altitudes, the concentration of air/oxygen is low.

Mountain climbers must therefore carry their own supply of oxygen for breathing.

(ii) Deep sea diving-Deep sea divers carry their own supply of Oxygen.

(iii) Saving life in hospitals for patients with breathing problems and during anaethesia.
