Why is an electric light bulb not filled with air? Explain why argon or nitrogen is filled in an electric bulb.
As the filament of the bulb is made from tungsten, so when we fill air inside the electric bulb this tungsten filament will burn quickly. So we fill unreactive gas like argon or nitrogen in the electric bulb to prolong the life of filament.
