Uses of Noble Gases
- Argon is frequently utilised in metallurgical operations to supply the required inert environment. When welding titanium, aluminium, stainless steel, and magnesium, this inert environment is crucial. Additionally, it is employed in the creation of titanium.
- The germanium and silicon crystals used in electric light bulbs, transistors, etc. utilise a little quantity of argon.
- When compared to other liquids, helium has the lowest boiling point. It is utilised to achieve the lasers' lowest needed temperatures.
- Helium is utilised as a flowing gas in liquid gas chromatography and as a cooling gas in nuclear reactors. It is used in helium-filled balloons and airships.
- To assess the local weather, helium balloons are employed. Although hydrogen is less expensive, helium is favoured since it is always available while hydrogen is more combustible. Therefore, helium is chosen in aircraft due to safety concerns.
- As nitrogen dissolves easily in the blood and causes a painful illness known as bends, divers use it to dilute oxygen over nitrogen in the gas cylinders they use. Helium poses a slightly lesser threat of bends than nitrogen.
- The reddish-orange glow that neon lights emit is due to the usage of neon in discharge tubes.
- Xenon and krypton are used in photographic flash units because they produce extremely intense light. Additionally, lighthouses employ it.
- Different colours of lights are produced using neon, xenon, and krypton.
