Answer 1

Answer:

When an electric current passes through a bulb, the tungsten filament gets heated up to such an extent that it reacts easily with the surrounding elements. For an electric bulb filled with air, the tungsten filament reacts with the oxygen present in the air, which is a supporter of combustion, resulting in the burning of the bulb. Hence, the bulbs are filled with inert gases that are non-reactive.
