What does a light bulb have to do with an electrical light source?
A light bulb is a source of electric light. In an incandescent light bulb, the glass bulb forms a protective shield around a glowing filament. The air inside the glass bulb is removed, or replaced with an inert gas. Electric current is passed through a thin metal filament (usually tungsten), which causes it to glow white hot, giving out light. The protective bulb stops the filament from burning up, as it has no Oxygen.
Why is a filament bulb not filled with oxygen?
Light in a lightbulb is produced by running a current through a wire with a high resistance. This creates a lot of heat, which when hot enough creates light. Imagine heating up a piece of steel until it glows. If the bulb was filled with oxygen, the tungsten filament would burn before it ever got to hot enough temperatures for our light needs. Therefore, we use argon so that while it gets hot, it doesn't burst into flames. Simple, really.
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.
How is light produced in an ordinary incandescent bulb?
Electric power is put trough a metallic filament inside a bulb that is filled with an inert gas. the filament is surrounded by the inert gas rather then air to stop the metallic filament from oxidizing when it starts to glow as a result of the electricity being run through it. the glowing filament produces the light.
What does the filament of a light bulb allows the light bulb to change electrical energy to?
The filament of a light bulb overs enough resistance to current flow, that the filament heats up so much that it will glow and produce visible light.
Why do you use Argon in a light bulb instead of oxygen?
The current flowing through the filament causes it to heat to a very high temperature - so high that is becomes incandescent (glows) and gives light. If the bulb was filled with oxygen then, at those high temperatures, the filament would oxidise - burn out - and the bulb would be "blown".
Why is there hardly any air in a glass bulb?
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!
Why are only inert gases like Argon used in an electric light bulb?
If the lighter bulb had oxygen in it , the hot glowing filament would react with the oxygen, thereby destroying the filament. If the filament is destroyed, then there is no light. So an inert gas is used, because it will not react with the heated glowing filament. Hence the filament stays alight.
What makes a light bulb shine brighter?
quality of reflector, type of light emission, (filament,gas filled)
Did a chemical change take place in a light bulb?
Possible oxidation of the metallic filament with traces of oxygen existing in the light bulb.
What stops the filament in a light bulb from Catching Fire?
For the filament tocatch fire you need to have oxygen present so depending on the type of light bulb it may be a vacuum inside or have some sort of inert gas inside that is not oxygen.
What type of light is a light bulb that uses a filament?
A light bulb that uses a filament is also known as an incandescent light bulb.
How the 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 .

Why is argon used instead on air in the light bulb?
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.
