Fire belongs to which state of matter

Question

Every thing is matter So In which state of matter fire will be considered? I haven't get it's proper answer.

Answer 1

Fire is just a very energetic gas.

It is made out of molecules (the products of the reaction and atmospheric gasses) moving very fast

Answer 2

Fire, chemical fire in particular, the kind we see everyday on candles and under saucepans, is actually just super-heated air. The atoms/molecules are so agitated that electronic transitions make it visible to us along with radiating heat which we feel.

There is a different kind of 'fire' though, which we find on stars or inside tokomaks and stellarators, this kind is fundamentally different in constitution from our ordinary household fire. In fact, in these 'fire's, atoms don't exist, the electrons have been ripped off and it exists as kind of a goo made up of electrons and individual nuclei, plasma that is. These can be incredibly hot, much much more than ordinary fire.

The 'state' of matter isn't of particular concern in science. My brother once asked, with a pensive look on his face, what state of matter would steaming, gooey rice be? I mean it flows. almost like a fluid under a noticeable tangential shear, yet occupies a fixed shape even when it isn't in a container.

Like all systems of classification, this division of matter into 'solids', 'liquids', 'gases'. 'plasma'or 'BEC' is taken too seriously by beginners in science.

Ice and liquid water are different states with the same chemical composition, hence they can be said to be more 'similar' in a sense than ice and calcite(at room temperature), both of which are solids.

This classification is based on similarities of mechanical properties. There are a whole range of materials that have intermediary properties and can't be strictly said to fall into either of the above categories. It just doesn't matter. These states are man-made simplifications to make sense of the incredibly varied and rich universe we live in, like a crutch, a rule of thumb.

Answer 3

Fire is actually a region where a combustion reaction takes place. If we talk about the various states present in this region, it could be gases which are a result of combustion, and very high temperature flames can even cause gas to change to plasma. The coloured object which we call fire actually is light energy being released which can't be classified into states of matter.

Answer 4

Fire itself isn't really a thing. And by thing I mean a construct of atoms. It's easy to rely too heavily on the concept that absolutly everything is a construct of atoms, but fire (although created by chemical reactions) is just simply an image. Similar to a rainbow and the northern lights, fire itself is just a bunch of excited energetic atoms emitting light. So if you were to define the atoms that emit the light as the fire itself, then it would be a gas.
