what is fire made of?

Answer 1

Fire is not an element.
it is a chemical reaction between oxygen and a solid,
its the same process as rusting but with a spark
and it happens much faster.

Answer 2

Fire, or flame, is primarily an extremely hot gas, even hot enough to give off light. It is mainly composed of oxygen, carbon dioxide, nitrogen, and water vapor.

Fire is a chemical reaction which creates a burst of heat and light. This is called ignition point, and what we see is a flame. When heat changes the state or shape of an objects, we call this combustion.

There are three main elements which are required to ignite a flame. Without any of these three elements, it is not possible to start a fire. These three elements are: Oxygen, Fuel and Heat.

Answer 3

Fire, or flame, is primarily an extremely hot gas, even hot enough to give off light. It is mainly composed of oxygen, carbon dioxide, nitrogen, and water vapor. In a solid, the molecules (what the objects are composed of) are very tightly packed together and are chemically bound, so it cannot change shape very easily. In a liquid, the molecules are not chemically bound, but they are packed very tightly together and interact strongly with their neighbors. In a gas the molecules are not chemically bound, and are not even packed close together, in fact, they are so widely spaced that they hardly interact with.

Answer 4

One thing almost nobody in the White Man's community considers is the fact that fire is actually a spiritual life form, in addition to a chemical/mechanical process.

Answer 5

Fire is the rapid oxidation of a fuel (combustion) with associated flame, heat, and light. The flame itself is a thin region of gas where intense chemical reactions are taking place. The reacting gas in this area is often hot enough to glow visibly, although some flames can be nearly invisible. Typical flames are just incandescent gas, and are not plasmas, as they are not hot enough to be sufficiently ionized.

Fires start when a flammable or combustible material with an adequate supply of oxygen or another oxidizer is subjected to enough heat. The common fire-causing sources of heat include a spark, another fire (such as an explosion, a fire in the oven or fireplace, or a lit match, lighter or cigarette) and sources of intense thermal radiation (such as sunlight, a flue, an incandescent light bulb or a radiant heater). Mechanical and electrical machinery may cause fire if combustible materials used on or located near the equipment are exposed to intense heat from Joule heating, friction or exhaust gas. Fires can sustain themselves by the further release of heat energy in the process of combustion and may propagate, provided there is a continuous supply of oxygen and fuel. Fires may become uncontrolled and cause great damage to and destruction of human life, animals, plants and property. Fires can also occur through instantaneous combustion. This highly disputed phenomenon is currently under research. It is known that this does occur in a vacuum but is disputed as to whether or not it occurs in nature.

Fire is extinguished when any of the elements of the so-called fire tetrahedron—heat, oxygen, fuel or the self-sustaining chemical reaction — are removed. The unburnable solid remains of a combustible material left after a fire are called ash.

A flame is an exothermic, self-sustaining, oxidizing chemical reaction producing energy and glowing hot liquid, of which a very small portion is plasma. It consists of reacting gases and solids emitting visible and infrared light, the frequency spectrum of which is dependent on the chemical composition of the burning elements and intermediate reaction products.

In many cases such as burning organic matter like wood or incomplete combustion of gas, incandescent solid particles, soot produces the familiar red-orange 'fire' color light. This light has a continuous spectrum. Complete combustion of gas has a dim blue color due to the emission of single wavelength radiations from various electron transitions in the excited molecules formed in the flame. Usually oxygen is involved, but hydrogen burning in chlorine produces a flame as well, producing the toxic acid hydrogen chloride (HCl). Other possible combinations producing flames, amongst many more, are fluorine and hydrogen, or hydrazine and nitrogen tetroxide. Recent discoveries by the National Aeronautics and Space Administration (NASA) of the United States also has found that gravity plays a role. Modifying the gravity causes different flame types. [1]

The glow of a flame is somewhat complex. Black-body radiation is emitted from soot, gas, and fuel particles, though the soot particles are too small to behave like perfect blackbodies. There is also photon emission by de-excited atoms and molecules in the gases. Much of the radiation is emitted in the visible and infrared bands. The color depends on temperature for the black-body radiation, and chemical makeup for the emission spectra. The dominant color in a flame changes with temperature. The photo of the forest fire is an excellent example of this variation. Near the ground, where most burning is occurring, it is white, the hottest color possible for organic material in general, or yellow. Above the yellow region, the color changes to orange, which is somewhat cooler, then red, which is cooler still. Above the red region, combustion no longer occurs, and the uncombusted carbon particles are visible as black smoke.

The common distribution of a flame under normal gravity conditions depends on convection, as soot tends to rise to the top of a general flame, such as in a candle in normal gravity conditions, making it yellow. In microgravity or zero gravity, such as an environment in outer space, convection no longer occurs, and the flame becomes spherical, with a tendency to become more blue and more efficient (although they will go out if not moved steadily as the CO2 from combustion does not disperse in microgravity, and tends to smother the flame). There are several possible explanations for this difference, of which the most likely is that the temperature is evenly distributed enough that soot is not formed and complete combustion occurs. [2] Experiments by NASA in microgravity reveal that diffusion flames in microgravity allow more soot to be completely oxidised after they are produced than diffusion flames on Earth, because of a series of mechanisms that behaved differently in microgravity when compared to normal gravity conditions. [3] These discoveries have potential applications in applied science and industry, especially concerning fuel efficiency.

Fire ecology is the study of the interaction of living things with fire.
