What does the bulb do on a light bulb?
It provides a protective, oxygen-free atmosphere for the filament, the glow wire. If the wire was to be heated in regular air, it'd burn and break immediately.
Why the electric bulb does not works if oxidation takes place inside it?
Because the filament will burn, and the filament is the part that produces the light.
Why is a light bulb sealed?
A light bulb is sealed to prevent air from entering the bulb, which can cause the filament to burn out quickly. The vacuum or inert gas inside the bulb helps to preserve the longevity of the filament and ensures consistent lighting performance.
Why is a filament light bulb not filled with oxygen?
A filament light bulb is not filled with oxygen because oxygen can cause the filament to burn quickly. The bulb is usually filled with an inert gas like argon to prevent the filament from burning out too quickly and to protect it from oxidation.
Why does a light bulb turn black?
A light bulb turns black when the filament inside it gets too hot and starts to burn, creating a layer of soot on the inside of the bulb.
How bulb light?
An electrical current is passed through the high resistance filament in the bulb, causing it to become white hot and so give off light. The inside of the bulb is filled with an inert gas, such as nitrogen, so the filament does not burn up .
How the bulb light?

Why does the filament of a light bulb not burn?
The filament of a light bulb does not burn because it is made of a material, typically tungsten, that has a high melting point and is able to withstand the high temperatures generated by the electric current passing through it. Additionally, the filament is enclosed in a vacuum or inert gas to prevent it from reacting with oxygen and burning up.
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.
Why do light bulbs burn out?
Light bulbs burn out due to the filament inside them breaking or wearing out over time, which interrupts the flow of electricity and stops the bulb from producing light.
Which gas in the air burn's out the filament?
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.
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.
