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.

Which gas is used in light bulb?
regular light bulbs have argon and/or nitrogen
Why argon and nitrogen is filled in an electric bulb?
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.
What are some of the components in a light bulb?
The bulb and the filament are the two main components of an incandescent light bulb.
When electric current flows through the metal filament of light bulb electric energy is converted to?
Heat and light.
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.
Is argon used in a light bulb?
yes argon is used for light bulb and it is not reactive
Which gas used in light bulb?
The gas in a light bulb is 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.
Which gas is present inside the electric bulb?
Argon
Why was argon gas chosen for a light bulb?
Argon is often used when an inert atmosphere is needed. It is used in this way in incandescent light bulbs to stop oxygen from corroding the filament. Argon is used in fluorescent tubes and low-energy light bulbs. A low-energy light bulb often contains argon gas and mercury. When it is switched on an electric discharge passes through the gas, generating UV light. The coating on the inside surface of the bulb is activated by the UV light and it glows brightly.
What elements light up a light bulb?
argon is an element that make up a light bulb
What gas is inside a light bulb?
The kind of gas that is in a light bulb is called Argon.
What elementes make up a light bulb?
argon is an element that make up a light bulb
In a bulb noble gas argon is used . why is argon is used instead of air in the light bulb?
It won't burn the filament.
How many hours did Thomas Edison's first light bulb stay on?
Thomas Edison crowns 14 months of testing with an incandescent electric light bulb that lasts 13½ hours
Which came first the telephone or the electric light bulb?
The electric light bulb came first but was patented later that the telephone was.
What gas stops a light bulb burning?
ARGON
