Helium is a colorless, odorless, odorless, inert gas that is gaseous at room temperature. Under normal conditions, helium does not chemically react with other elements and compounds. Because it is known as "lazy", we call it inert gas. Does suffocation explode? Helium is an inert gas that is "very lazy" and doesn't play with fire!
Does suffocation explode? Helium is a rare gas and the peripheral electronic layer reaches a steady state. Helium is the most difficult gas to liquefy, extremely inactive, unable to burn, and does not support combustion. It can be extracted from natural gas containing up to 7% of helium in the industry. The content in the air is very small, and it is very difficult to extract from the air. The cost is very high and the price is very expensive. Domestic helium is imported from the United States. Therefore, suffocation is not dangerous at all, but domestic helium resources are scarce, so the price is more expensive.
Is it going to explode? Newrid gas small series takes everyone to see what is the use of radon in life. Because the density of helium is small and chemically stable, the safety is higher but the cost is higher. Filling the balloon with hydrogen is small, but the balloon is flammable, explosive, and less safe, so at the birthday party, wedding ceremony, party A colorful balloon can be seen everywhere on paty. Because helium is very light and non-flammable, it can be used to fill airships, balloons, thermometers, tubes, diving suits, and more.
Helium can also be used as a shielding gas for atomic reactors and accelerators, lasers, rockets, smelting and welding. It can also be used to fill bulbs and neon tubes, as well as to make foam.
Since helium has a low solubility in the blood, it can be added to oxygen as a breathing gas for divers. Is it dangerous for hernia? Helium is used in deep-sea breathing gas to show that helium is not dangerous!
The temperature of liquid helium is close to absolute zero (-273 ° C), so it is used as a superfluid in superconducting research to make superconducting materials. Liquid helium is also commonly used as a coolant and refrigerant.
