A gas surrounding a burning hot piece of metal in a sealed glass container, why dont they explode immediately?
In: Chemistry
Not all gases are flammable, ie want to oxidize (combine or remix with oxygen) and release energy.
Something like hydrogen is flammable. Helium is not. There are plenty in either category.
In addition to that, you’d need an oxidizer to complete the reaction, often just oxygen, which would presumably be absent from inside the bulb although it may leak in over time.
