It isn't.
Argon is what fills and incandescent bulb. Argon is an inert gas and won't oxidize the tungsten filament even at very high temperatures, so the light bulb lasts months rather than minutes.
Having a gas in there at all helps diffuse heat and also allows the filament to last longer than a vacuum would.

Which gas present in bulb?
Gas is not used to make light bulbs emit light. What happens is that the wire is really thin so the electrons come across high resistance and become very hot, therefore creating light. However low pressure inert gases such as argon, neon or nitrogen are used inside the light bulb to keep it safe, and stop an explosion.
Which gas is used in light bulb?
regular light bulbs have argon and/or nitrogen
How does argon let you use an electric light bulb for many hours?
When the filament of a bulb becomes hot, it can react with the air around it, causing it to change size and / or shape, breaking the filament. Argon is unreactive, and so when this gas surrounds the filament, it prevents it from reacting, so preserving it for a longer period.
Can you use a regular bulb in a freezer?
A light bulb is already mostly frozen. The glass parts are in a state called a "glassy solid". The metal filament, filament supports and base are in a state we call a "solid". The only part of a light bulb which is not already frozen is the dilute gas inside it, which is normally a mixture of nitrogen and argon. Argon freezes at -200 C and nitrogen freezes at -210 C. So if you cool a light bulb down to -210 C (-346 F) then it will become completely frozen. Of course, it will still work.
What is the gas inside a filament lamp?
Most common house hold light bulbs are really just evacuated to really low pressures and contain a tungsten filament. the reason being is that tungsten has high resistivity and low corrosive properties. they used to use carbon in the beginning. the reason for the vacuum is to prevent evaporation of the filament.ArgonUsually they are filled with an inert gas such as nitrogen and others are filled with a gas containing low pressure mercury vapour and argon, xenon, neon or krypton.An inert gas such as Argon
The gas usually filled in the electric bulb is?
Electric light bulbs are commonly filled with argon gas. The other ones could also be either helium, neon, nitrogen or krypton.
Why are electric bulbs filled with argon and nitrogen?
cuz it slows down the evaporation of d filament of the bulb....so that d bulb doesn't stop working.
Which gas is in electric bulb?
Modern bulbs are usually filled with a mixture of argon and nitrogen. More rarely, some bulbs are filled with pure argon, krypton or xenon. The earliest bulbs weren't filled with any gas, but had vacuum inside.

What are the gasses they put in a bulb?
nitrogen , and argon gas
Will an electric bulb glow when it is filled with vacuum instead of an inert gas like argon or nitrogen?
"filled with nothing" ??? yes is the answer your looking for, but the bulbs we use today are optimized to work with whatever gases each company uses. Oxygen is the destroyer of fillaments (remember the old flash bulbs?)
Which gas is present inside the electric bulb?
Argon
Why are light bulbs filled with argon and not air?
If you use air instead of argon to fill a light bulb, the air will burn the light bulb.
Is the gas in fluorescent bulb poison?
Argon & Nitrogen are both toxic.
Does a light bulb contain nitrogen?
An ordinary household Incandescent type light bulb does not contain nitrogen gas. The bulb contains a vacuum surrounding the incandescent elements. There are other kinds of lights that do contain gases, Like Neon, argon and nitrogen but they are not commonly found in homes and and are not generally made as "Bulbs" being more commonly made as gas filled tubes.
Which gas is filled in light bulb?
Light bulbs are filled up by Neon or Argon gases, because they are inert.
Is a light bulb filled with Nitrogen?
yes and other gasses
