Many times we need a substance that does not react. Inside of electric light bulbs we find argon so that the filament will not burn up. Noble gases are also used in neon lights for advertising(orange) and other noble gases give different colors.

Inert gases are often used as an "inert atmosphere" for chemical reactions (many of which lead to important pharmaceutical drugs).
They are also found in between double paned glass, where they act as an insulator. Also found in neon lights. Please note that freon is *not* a noble gas, but rather a chlorofluorocarbon (CFC, CFC-12 to be exact).

Noble gas such as helium is used lift ballons, blimps, and air balloons. In addition, at extreme low temperature, helium is use to cool metals.Helium is also a proactive gas that help grows silicon, and germanium crystals. Helium even changes a person's voice when inhale.
Hope it helps.

for sure it does. Politics determines each thing from how a lot you pay for petrol, beer, and food, to how a lot tax you pay, what your toddlers study in college, and no matter in the adventure that your garbage is accrued. Politics is everywhere, and impacts a hell of quite some our each day lives. in basic terms because you imagine that's uninteresting does not advise it would not be counted. also, philosophy is not frequently a 'useless paintings variety'.

Argon is used in welding. The oxygen in air casuses problems if it contacts metal when you are welding it. So sometimes argon gas is used--they blow it at the welding area and it displaces the oxygen.

Helium for hot air baloons and funny voices.
Neon for lighting shop signs.
Xenon for car head lights

Besides neon signs, halogen lightbulbs....laser pointers, the goodyear blimp (helium) and such things....freon on the fridge/freezer
Chemistry lab lol... hmm...
