Oxygen is the gas in the air that burns out the filament in an incandescent light bulb. When the filament reacts with oxygen at high temperatures, it oxidizes and eventually burns out.
The hot filament in an incandescent light bulb is protected by a glass bulb filled with an inert gas, such as argon or nitrogen. This gas prevents the filament from reacting with oxygen in the air, allowing it to glow and produce light.
Hi! This is the question for this question! Because air was contained with oxygen and oxygen so oxygen with smallest heat it burns down the filament! This is also evacuated and filled with a gas which does not react with the red hot filament. So .... if air present the filament would quickly oxidise and fail to light up!
Argon is used in light bulbs because it is an inert gas, which means it does not react with the filament or the glass envelope of the bulb. This helps to extend the life of the bulb by preventing the filament from degrading. Additionally, argon helps to reduce the rate of evaporation of the filament, leading to a longer-lasting bulb.
Light bulbs are filled with argon instead of air because argon is an inert gas that helps prevent the filament from oxidizing and burning out quickly. Air contains oxygen, which can cause the filament to degrade faster due to oxidation. Argon creates a more stable environment inside the bulb, prolonging the life of the filament.
The filament in an electric bulb is made of tungsten, which has a high melting point and can withstand high temperatures when electricity passes through it. When electricity flows through the filament, it heats up due to its high resistance, causing it to glow and produce light. The filament is enclosed in a vacuum or an inert gas inside the bulb to prevent it from burning up.
