Question

Argon is filled in electric bulb ? Give reason​

Answer 1

Answer:

Argon gas is an inert gas used in electric bulbs to prevent corrosion of its tungsten filament. Since it doesn't react with tungsten, it stops the filament from burning away in the presence of oxygen.

Answer 2

The heat from the tungsten filament generates light and the argon helps prevent the filament from decaying. Simply having air in the bulb would not work as the filament would react with the oxygen in the air and burn out the tungsten.
