Give one use of Argon , Helium & Neon .
Answers
Answer:
Argon is also used to form inert atmospheres for arc welding, growing semiconductor crystals and processes that require shielding from other atmospheric gases. Neon is also used to make high-voltage indicators and switching gear, lightning arresters, diving equipment and lasers. ... It is chemically inert, but radioactive.
Answer:
(1) Uses of helium (He) :
i)A mixture of helium (85%) and oxygen (15%) is used for filling balloons.
ii) A mixture of helium and oxygen is also used for respiration by sea divers instead of air because helium is less soluble in blood than nitrogen under high pressure. It is also used for treatment of asthma.
iii) Heliunm is used in producing inert atmosphere in metallurgical operations and welding or metals.
(iv) Liquid helium is used in producing low temperature rcquircd for research.
(v) Helium is also used in producing lasers in low temperature gas thermometry.
(vi) It is used in magnetic resonance imaging.
(vii) It is used as a shielding gas for arc welding
(Viii) It is used in supersonic wind funnels.
(ix) Helium nucleus 1s used as anbombarding particle for disintegration of atoms.
(2) Uses of neon (Ne):
i) Neon is used in the production of neón discharge lamps and signs by filling Ne in glass discharge tubes.
(ii) Neon signs are visible from a long distance and also have high penetrating power in mist
(iii) A mixture of neon and helum IS used in voltage stabilizers and curent rectuhers.
(IV) Neon is also used in the production of lasers and fluorescent tubes.
(3) Uses of argon (Ar) :
I) Argon is used to fill fuorescent tubes and radio valves.
(ii) It is used to provide inert atmosphere for welding and production of steel.
iii) it is used along with neon in neon sign lamps to obtain different colours.
iv) A mixture of 85% Ar and 15% N, is used in electric bulbs to enhance the life of the ilament.
