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.
Modern light bulbs don't hold a vacuum. Instead they are filled with an inert (electrically non-conducting) gas such as Nitrogen. An inert gas is used to fill the bulb (instead of just pumping out almost all the ordinary air to leave a near-vacuum) because the action of filling the bulb with an inert gas flushes away ALL of the ordinary air. In addition the inert gas has the very useful physical property of helping to conduct heat from the glowing filament to the glass bulb. This allows the whole surface area of the glass bulb to radiate heat into the surrounding air. It is important to understand that the inert gas does not allow the filament to "burn away" as it would if some air were still present in the bulb. This sometimes happens if a light bulb gets knocked and gets even a tiny crack in its glass bulb: the oxygen present in ordinary air will quickly make the filament burn away. So, to summarize, the inert gas which is used to fill the glass bulb allows the filament to glow very brightly without burning and conducts the heat produced by the filament away to the glass bulb.
Incandescent bulbs can use Argon or Krypton, which are inert. These gasses help slow down the decay of the tungsten filament. Halogen bulbs use a halogen (column 17 element) such as iodine to react with the hot tungsten atoms and allow the filament last longer.
Neon lights use neon gas. Xenon gas is used in strobe lights. These are also inert gasses.
Fluorescent bulbs typically use Mercury vapor.
That powder is Talc, it is used to coat the inside of the bulb to make the light more opaque so that it is less harsh on the eyes.
a filament
Light bulb fuses when the filament inside gets overheated due to excess load, and melts, causing it to break.
Glass is the insulator in a light bulb. The base has a heavy piece of glass to separate the ring from the center, and there is a glass support inside the bulb to hold up the filament and separate the wires going to the filament.
Well. A light bulb lights up because the atoms and electrons clash together which causes an electrical charge. And then it magically lights up the light bulb. By:?
usually Nitrogen.
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 .

Yes, the inside of a light bulb is a partial vacuum.
the wire in your light bulb is a resistor :)
yes and other gasses
The kind of gas that is in a light bulb is called Argon.
Answer:The filament inside the light bulb reaches over 3000 degree Celsius.
regular light bulbs have argon and/or nitrogen
Tungsten
You do not. CO2 has nothing to do with the creation of a light bulb. A typical incandescent bulb has a vacuum inside. No light bulb uses CO2.
