Which gas present in bulb?

Answer 1

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.

Answer 2

Which one? Ordinary filament lamps - GLS are nitrogen-filled. Halogen filament lamps are usually filled with nitrogen plus a trace of bromine. Xenon filament lamps are filled with xenon, etc etc etc Domestic fluorescent lamps are filled with Mercury vapour and usually an inert gas. Discharge lamps are filled with gas mixtures specific to the lamp design and principle of operation.

Answer 3

The gas present in a light bulb is typically an inert gas like argon or krypton. These gases help prevent the filament from evaporating too quickly by slowing down the oxidation process.

Answer 4

The gas usually argon and/or nitrogen.
I dont think it is gas It is electricity.

Edit: Usually a halogen, the most common being Neon.

Answer 5

Argon is in incandescent light bulbs, but neon lights actually have different gases to product the different colors. Neon, krypton,argon

Answer 6

Usually Argon or Nitrogen

Answer 7

Any inert gas, argon for one.

Answer 8

argon
