Fire is a phenomenon of combustion manifested in intense heat and light in the form of a glow or flames. The word fire when used with an indefinite article is commonly used to describe either a fuel in a state of combustion (such as a campfire or a fire in a fireplace or kitchen stove) or an instance of violent, destructive and uncontrolled burning (such as a wildfire and fires in buildings and vehicles).
Fire is not a state of matter, it is an exothermic chemical reaction accompanied by intense heat released during a rapid oxidation of combustible material.

Fire is energy.
It is a chemical reaction involving fuel, a heat source and oxygen.
Fire isn't matter because it consumes the fuel and converts it to another state of matter--the smoke. Only a chemical reaction does that. Fire isn't a gas, it generates and consumes gas. It also can be blocked by a metal screen, which even heavy gases can pass though.
Fire is energy because it changes the state of matter, it consumes matter and it generates energy--heat.

Fire itself (the actual flames) is a chemical reaction that yields heat and light, which are both forms of energy.
It needs three substances:
1) Fuel
2) Air or another oxidizing agent
3) Heat
The heat and light can be minimal (a candle), intensely concentrated (a fully involved, multiple-storied structure fire), or widespread (a forest fire).

What we see as fire can be made of two components: heated, glowing particles carried by hot gases, or the emission of radiation by gases hot enough to be ionized. In a wood fire, the chemical reaction of rapid oxidation of the wood generates hot gases that carry tiny carbon particles which glow when hot. Put a cold piece of metal in a wood flame and these carbon particles will deposit on the metal as soot. Ionized atoms also send out illumination, usually these are more colored than glowing soot. An example of this is the candle flame: the blue flame near the wick is ionized gas radiation, the yellow flame above is glowing carbon. Chemicals vaporized and ionized in hot gases also color the flame, sodium giving a yellow color, lithium a red color. The flame test is one way to identify certain elements in chemical analysis.

I think that depends on your definition of fire. When you see fire, you are seeing a glowing gas. The chemical reaction is causing heat which causes the gas to glow which emits energy.

Fire is a chemical reaction which requires 3 things in order to exist.
1 Fuel, the material your going to burn.
2 Oxygen, just like us fire uses oxygen and releases C02.
3 Heat release, fire must release the heat it produces.

It is matter becoming energy through rapid oxidation caused by heat.
Very simple.

it is energy given off by burning gas. so i'd say it is energy in the form of photons and heat.
