Question

Why are gas like argon and nitrogen filled in bulbs?

Answer 1

Explanation:

Filament will evaporate in vacuum condition. The closed glass chamber of the bulb contains, an inactive (inert) gas, Argon. The glass chamber can't be filled with air as the presence of oxygen will cause the filament to burn, i.e. react with oxygen. ... Nitrogen is also used like argon

Thanks!!
