aquarian93:
oh, bt argon is more abundant in air, 0.93%.
 bt helium is very less, 0.02%

MR.BooMBastiC:
really..........these gases compose of 0.8% of the air.....

so do u think they r abundant....????

78% nitro
21% oxygen
1% other gases....out of these 0.2% is co2!!!!!

IGs:
being more abundant is correct because argon is much more available than helium..so its much cheaper
and for gp7 m.p and b.p do increase thats why they change from gases to solids
and for stainless steel ofcourse it's railway lines because it was written that its very expensive so according to logic its right

MR.BooMBastiC:
i think maybe u misunderstood da q..
they said argon is used in filament lamps...so that they can last 4 a longer time......
which of da following properties is suitable for its use.....

so da options they gave wr totally irrelevant to its use...

no dude.....ARGON IS USED BECAUSE IT IS UNREACTIVE[INERT]

ITS NOT used because it is abundent or denser...tec..
