Fire changes solids/liquids/gases into gases... much like the human digestive system...

What you see as fire are either glowing particulates or gases that result from the chemical reaction called combustion (usually oxidation) that is so exothermic that these are at a very high temperature--high enough to emit light. In some cases, the reaction products include gases at high enough temperatures to ionize (becoming a plasma) which can emit light. Sometimes both gases and particulates are giving off light. The shape of the fire is due to the fact that the combustion products are carried by heated gases that rise rapidly. In a wood fire, what we see are glowing particles; in an acetylene flame, it's ionized gas.

Technically, fire is first a solid (fuel) and a gas (oxygen).

Then, there is a very brief and small plasma state involved as the reaction occurs, depending on the pressures.

in the end, there is still some solid, in most cases, like soot or ash, and gasses that are more complex and hotter, more energetic.

However, chlorine can also support flame.

Fire is a chemical reaction between an oxidant and fuel. Heat is generally necessary to initiate the reaction, but there are certain elements, when combined, will produce spontaneous combustion. This is the most basic of answers.

I hope this helps.

Fire is just heat and light, with some water vapour possibly mixed in, depending on what you are burning.

A plasma is defined as an ionised gas.

Fire is the result of a reaction. When heat, oxygen, and a flammable fuel source combine, a fire results. Just like when the filament in a light bulb is heated, it emits light. Light does not fall under any of the states of matter; it is the result of a reaction: the filament being heated.

Fire is a visible combustion of fuel, and in some chem classes, I've been told it is a gas. When you burn gasoline, you're not igniting the liquid, you're burning the vapour of the gasoline, so I think it is a visible heat transfer.

Fire is not matter, it's energy that begins with a chain reaction involving a flamable object and a large amount of heat.

Fire is not matter , its a type of energy , light and heat energy , hence cant be solid nor liquid nor gas nor plasma! GREAT QUESTION THOUGH!!!

Fire is basically excited atoms in an ionized gas trail. Once the atoms drop back to their non excited state, there is no light, but you can see the smoke from whence they came!
