The flames consist of hot reacting gases, which emit light in the frequencies from the emission spectrum of the hot molecules and radicals, giving rise to colors depending on the chemical composition... | The part of fire that you can see is light, which can't exactly be described as matter in and of itself, so it doesn't have a fully defined material state. It's akin to asking whether a radio wave is a solid, liquid or gas - it doesn't fit that model at all.
However, if we are to relax the semantics a little, the matt... |
