What are the uses of noble gases?

takshila learning educate yourself PA What are the uses of noble gases ? TM 1. In metallurgical processes , argon is widely used to provide the necessary inert environment . This inert atmosphere plays an important role in the welding of titanium , aluminium , stainless steel and magnesium . 2. Argon is used in limited quantities in germanium and silicon crystals are used in electric bulbs and transistors . 3. Helium has the lowest boiling point . This is used to obtain the minimum temperature required by the laser . 4. Helium is used as a cooling gas in nuclear reactors and as a flowing gas in liquid - gas chromatography . It finds its application in aeroplanes and helium balloons . 5. Helium balloons are used to test the climate of a particular region . Although hydrogen is cheaper , helium is preferred over hydrogen because hydrogen is more flammable because helium is more readily available . Therefore , helium is preferred over aircraft due to safety issues . 6. Nitrogen is used to dilute the oxygen in gas cylinders used by divers , as nitrogen readily dissolves in the blood , causing a painful condition called bend . Helium's ability to form curves is slightly less than that of nitrogen . 7. Neon is used in discharge tubes , which is the reason behind the reddish - orange glow produced by neon light . 8. Xenon and krypton find their application in photographic flash units due to the production of very bright light . It is also used in lighthouses . 9. Neon , xenon and krypton are used to make different coloured lamps . takshila learning educate yourself ТМ For More information Visit : www.takshilalearning.com Mail us at [email protected]
