The filament in the light bulb is heated to a very high temperature. At such a temperature oxygen from the air would oxidise the metal(s) in the filament and thereby destroy the bulb. Using an inert gas such as argon in the bulb prevents such oxidation.

In a bulb noble gas argon is used . why is argon is used instead of air in the light bulb?

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.


Which gas used in light bulb?

The gas in a light bulb is Argon


Is argon used in a light bulb?

yes argon is used for light bulb and it is not reactive


Can a light bulb work with just oxygen instead of argon?

No. Light bulb filaments become extremely hot when in use, and oxygen, which is highly reactive, would cause the filament to burn away in a matter of seconds. Argon is used because it is inert, and thus will not react with the filament.


Which gases are used in a light bulb?

argon and xenon i think


Can argon be put in a light bulb?

Yes and it is often used


Why do you use argon in a light bulb?

Argon is used in a light bulb to fill the space inside the bulb and prevent the filament from evaporating. It also helps to extend the lifespan of the bulb by reducing the oxidation of the filament. Additionally, argon improves the efficiency and brightness of the light produced by the bulb.


Why is argon use in a light bulb?

Argon is used in a light bulb because it is an inert gas that helps prevent the evaporation of the tungsten filament. By creating an inert environment, argon helps increase the lifespan and efficiency of the light bulb.


Why is argon used in light bubs instead of vacuum?

argon is no reactive how ever vacuum


What is the gas that does not react at all and it is used in light bulbs so the metal in the light bulb can get very hot without burning?

The gas that does not react and is used in light bulbs is called argon. Argon is an inert gas that helps prevent the filament in the light bulb from oxidizing and burning out at high temperatures by creating a non-reactive environment inside the bulb.


What property of argon is used In a light bulb?

Argon's property of being inert (chemically non-reactive) is used in a light bulb. It prevents the filament from evaporating by creating a stable environment inside the bulb, allowing the filament to glow brightly and last longer.


Which gas is used in light bulb?

The gas most commonly used in incandescent light bulbs is argon, which helps to prevent the filament from oxidizing and burning out too quickly. Other gases, such as nitrogen and krypton, may also be used in combination with argon to improve the efficiency and lifespan of the bulb.
