what is fire? is it a gas or what? what is it made of(molecules, atoms, photons, etc.) and what kind of that(IE, what/which atoms, what/which molecules,etc.)
is white hot fire real? where the hell would you see it? does anything burn that hot?
why do different temperatures of fire have different colors?
wow thats like 80 questions isnt it?

fire is the visual portion of gases that have been energized to the point of emitting light. when something is highly energized, it attempts to rid itself of all that energy with one way being through emitting radiation. A large portion of the radiation emitted by a highly energized gas is infrared, which we feel as heat, but some of it will be in the visible spectrum which we see as fire. compounds become highly energized for a variety of reasons, but the most common one your probably familiar with is combustion. combustion is the chemical reaction between some compound (like butane from a lighter or cellulose in wood) and oxygen in the atmosphere. that reaction causes the molecules involved to become highly energized and thus produces heat and light.
fire can be a variety of colors, which is a reflection of how highly energized a compound is. a more energetic compound releases higher energy light waves. cold flames are red, orange, or yellow, like you see from a lighter or a campfire. higher energy flames are white or blue. you'll notice when you use a lighter that the very bottom of the flame is blue, this is because that's the hottest part of the flame. some compounds do burn with a pure white flame, such as magnesium metal, but the difference between white and blue is not always a matter of temperature so much as it is a reflection of how cleanly the flame is burning.
when a compound becomes immensely energized (such as the core of the sun), the gases can turn into a fourth state of matter, plasma. a compound becomes plasma when it is so hot that the electrons begin falling off their respective nuclei. plasma often gets ignored as a state of matter because we rarely see it on earth, but it happens in all stars. many stars glow blue or white, which is again a reflection of how much energy they are emitting.

Fire is a result of an oxidation chemical reaction. Iron rusting is the same thing, except that it is very slow. Rapid oxidation can cause smoke and then fire as more energy is given off. Different chemicals can also produce different colours when burned. Watch someone who is using a
welding torch. You see fire so white hot it will blind you. Oxidation involves physical changes, like gases, ashes, smoke, colour, shape,and state.

Fire is not matter. It is a form of energy.
However, Lighting is PLASMA. The 4th form of matter composed of highly heated particles.
