Question : Which of the following gases is used in a bulb?
Option 1: Hydrogen
Option 2: Carbon dioxide
Option 3: Carbon monoxide
Option 4: Argon
Correct Answer: Argon
Solution : The correct option is Argon.
Argon gas is found in many light bulbs, notably incandescent lamps. Argon is frequently used as a filler gas in incandescent bulbs to create a low-oxygen environment that prevents the filament from oxidizing and burning out. The inclusion of Argon gas contributes to the bulb's longevity and efficiency by lowering filament evaporation.
