Oxygen can rapidly oxidize metals and other materials in the presence of heat, so it is not compatible with the heated filaments or ionized gases within a light bulb.
The development of partial vacuums and use of inert gases (mostly nitrogen) allowed early light bulb filaments to become hot enough to glow without being burned up. Because metals conduct current better than their oxides, oxidation of filaments and conductors is also avoided.

∙ 16y agoOrdinary household light bulbs, or incandescent bulbs, are made with a tungsten filament that glows when electricity passes through it. The filaments need to be in a vacuum because if they are exposed to air they would oxidize, or rust, very quickly and would not provide light for a very long time. In other words they would burn out too fast.

What does 3157k mean in light bulbs?
3157 is the bulb type, the "K" means the bulb is filled with the inert gas Krypton.
Why does an electric bulb bang when it is broken?
Light bulbs have most of the air removed, that is there is a partial vacuum inside the bulb. So, when they break atmospheric pressure pushes the on the glass where it is weakened and air rushes somewhat violently into the bulb.
What is the difference between a water balloon and a normal balloon?
A water balloon is filled with water, and other balloons are filled with air or helium.
When you fill me still i look empty what am i?
A glass jar filled with air
What does the nitrogen inside a light bulb do?
Yes, modern incandescent bulbs are filled with an inert gas (argon,) but with a bit of nitrogen. Nitrogen is used because argon supports long sparks and leads to electric arcs and exploding light bulbs, and nitrogen interferes with this effect.
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.
Why is the inside of he bulb containing the magnesium is filled with a ''noble'' gas instead of air?
It might be metals or nonmetals in the bulb
When water in a beaker is heated bubbles come out to the surface why?
When a droper is dipped into water and its bulb is pressed air bubbles seems to occur in water because the dropper was filled with air before it was dipped in water and when we press the bulb air comes out forming air bubbles and the space is filled with water .
What would happen inside a light bulb if it was filled with air?
It would no longer work. Light bulbs are usually under vacuum and if air gets in the filament blows.
What is a dropper and what are its uses?
A dropper simply is a small tube with a air-filled bulb at the top. You squeeze the bulb at the top and whatever substance the tube is submerged in, it will be pulled up into the tube. After that, you lightly squeeze the bulb again to release the substance in the tube out.
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!
What is a soccer ball filled with?
It is filled with air. A soccer ball is filled with foam. Air
What gases are in a light bulb?
Light bulb is filled with inert gas or simply a vacuum.
Is a fluorescent bulb filled with gas at a high pressure?
no
How does the ink dropper works?
ink dropper works on the principal of air pressure. when we fill ink inside the dropper we have to press it's bulb(upper,soft rubber portion),because of which the air inside the dropper is removed and low air pressure region is formed. when we dip it in the ink,the space is filled with ink,which remains retained in it unless we press the bulb again.
Is hot air balloons filled with helium?
No, it is filled with heated air.
Is a hot air balloon filled with nitrogen?
It is filled with heated air. Since air is mostly nitrogen, a hot air balloon is mostly filled with nitrogen.
