Oxygen gas forms the compounds with nearly all the elements except the inert gases , It is compressed in iron cylinders to be used in mechanical ventilation for the patients who suffer from breathing difficulties and it is used during surgeries .

Oxygen gas is used by the mountaineers at high latitudes during climbing as oxygen gas is heavier than the air , so its percentage decreases when we rise above the Earth’s surface .

Oxygen gas is used by underwater divers during diving , and the astronauts use it during  walking in the space , Oxygen masks are used to ease various medical disorders , like hypoxemia , asthma , the heart and the vascular diseases .

Oxygen gas is used in the formation of the water that is composed of oxygen combines with hydrogen , It is used to kill bacteria causing gangrene ( as it is poisonous for them ) and it is used to treat carbon monoxide poisoning as well .

Oxygen gas combines with acetylene gas to produce oxy-acetylene flame which is used for cutting , welding and melting of metals as its temperature rises to 3500 degree Celsius .

Oxygen gas is used in the production of iron and steel in the blast furnaces using hot oxygen air,  It also burns off carbon impurities , Even in mines , it is employed as a part of explosives for blasting rocks .

Oxygen gas forms the ozone layer in the atmosphere that protects the Earth from harmful radiations that come from the Sun , Ozone molecule is composed of three oxygen atoms ( O3 ) .

Oxygen gas is used in the manufacture of nitric acid , sulfuric acid , other compounds , and acids , Ozone is used in different chemical reactions to improve the rate of reaction and ensure the fullest possible oxidation of the compounds .

Oxygen gas is used in for the combustion to produce the energy in the automobiles , the airplanes , the ships , the generators , the industrial process , Liquid oxygen gas is used in burning of fuel in the spacecraft for generating the required thrust in space where there is neither air nor oxygen .

Oxygen gas is used for the environmental protection in the domestic and industrial waste water treatment plants and facilities , and also it is used in the conversion of iron ore into steel .
