Does helium burn when it meets fire? Is helium flammable and explosive

Helium does not burn when exposed to fire. Because helium is a non-flammable gas.

Helium, known as helium in English and symbolized as HE, is a colorless and odorless gas at room temperature and atmospheric pressure. The amount in the air is about one part per million, which is the critical temperature that humans have discovered.

The lowest substance. It is dark yellow when discharged at low voltage.

Helium cannot be cooled to absolute zero by simply cooling a saturated liquid.

And curing. For helium to solidify, the corresponding pressure must be applied. In it, helium transforms a normal liquid, or somewhat, from a normal liquid into a fluid with unique properties. On July 10, 908, Dutch physicist Annis liquefied helium for the first time.

Helium is a monoatomic gas with chemical properties.

Inactive. Helium generally does not form compounds, and can form HE ions, HEH and molecules when excited in a low-voltage discharge tube.

No. Helium is an inert gas that does not burn no matter how high the temperature is.

The ignition point of helium is about 50 million degrees Fahrenheit, 10,000 degrees Celsius, and after the combustion and fusion of helium, carbon and oxygen will be produced.

It depends on the temperature of the fire, and the temperature of the fire must reach the ignition point of helium.

Helium is non-flammable and explosive. Helium itself does not **, and helium is an inert gas.

It is not easy to react with other substances, and it is not easy to have chemical reactions.

**, relatively safe. Helium is an ideal gas.

It is an ideal gas for vapor pressure thermometers at very low temperatures. It can also be used as a pressure delivery agent and booster for rocket liquid fuel, and is widely used in missiles and spacecraft.

and on supersonic aircraft. <

A mixture of helium and hydrogen occurs when it encounters an open flame**.

All flammable gases, vapors of flammable liquids, and combustible dusts are mixed in flammable gases, and after reaching a certain limit, ignition may occur. The ** that occurs during ignition is generally a chemical change, but sometimes, such as tires**, boilers**, is due to the increase in the air pressure of the container, which is a physical change.

If the volume of a flammable gas in a flammable gas is below or above the limit, ignition will not occur. Oxygen is also not necessarily required for chemical reactions. For example, octanitrooctene is a nitro compound, which does not need oxygen to participate in chemical reactions, and only produces nitrogen and carbon dioxide, two non-toxic gases.

I hope I can help you with your doubts.

This depends on the ratio of helium to hydrogen, if it reaches the **limit of hydrogen**, it is easy to happen**. After all, hydrogen is relatively lively, flammable gas, thank you.

Flammable gases are easy to ignite when mixed with oxygen or air** Hydrogen is a flammable gas and is easy to ignite when mixed with air**, so it is in line with the topic;

Carbon monoxide is flammable, carbon dioxide cannot be burned, cannot support combustion, and does not occur in case of open flame**, so the option is wrong;

Oxygen can support combustion, helium can not burn, can not support combustion, and will not occur when encountering open flames**, so the option is wrong;

The main component of natural gas is methane, methane is a flammable gas, oxygen can support combustion, and it may occur in case of open flame**, so the choice is correct

Therefore, C
