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

no dude.....ARGON IS USED BECAUSE IT IS UNREACTIVE[INERT]
ITS NOT used because it is abundent or denser...tec..

By the way all group zero gases are inert n they do not react argon i agree creates an inert atmosphere but der dey wanted to noe wen both of dem r inert den why onli argon is used so it has to be bcoz it is more abundantly found compared to the others
