Oxygen is flammable, not combustible.
Flammable gases are gases that can burn in air, usually with a low ignition point, such as hydrogen and methane. These gases can react with oxygen in the air to produce a flame and release a large amount of energy.
Oxygen is a diatomic gas, consisting of two oxygen atoms. Its molecular structure determines that it is a strong oxidizer, capable of reacting with many substances. Therefore, when oxygen encounters flammable gases, it reacts rapidly with these gases, thus accelerating the spread of flame and the release of energy. This is the reason why oxygen acts as a combustible gas.
Oxygen itself does not burn because it is not flammable. When it encounters an ignition source, oxygen will only support the combustion of the flame and will not burn itself. Therefore, extra care needs to be taken when using oxygen to avoid contact with flammable gases or substances to prevent dangerous situations such as explosions.
Oxygen is a flammable gas, not a combustible gas, because it is a strong oxidizing agent by its chemical nature, reacting with combustible gases and accelerating the spread of flames and the release of energy. Extra care needs to be taken when using oxygen to avoid contact with flammable gases or substances.
Oxygen applications:
1, medical field: oxygen is very important in the medical field. For patients who need supplemental oxygen to maintain breathing, oxygen cylinders and oxygen concentrators are essential equipment. Oxygen can also be used to treat some diseases, such as asthma, chronic obstructive pulmonary disease and so on.
2, industrial field: in the industrial field, oxygen is widely used in cutting, welding, smelting and other processes. These processes require high purity oxygen, which can be supplied in stable and large quantities after compression, liquefaction or adsorption.
3, Laboratory and research: In the field of laboratory and research, oxygen is often used in experiments and research, especially those that require high or low oxygen environment.
4, aerospace: in the field of aerospace, oxygen is indispensable. Oxygen systems in airplanes and spacecraft provide passengers and crew with the oxygen they need to breathe.
5, diving: oxygen is also essential in diving activities. Divers need to breathe oxygen to sustain life, and also need to cope with the demand for oxygen in high-pressure environments.
6, fuel: oxygen can react with certain substances to produce energy. For example, rocket engines use liquid oxygen as an oxidizer to react with fuel to produce thrust.
