What does fire do to air?

changes oxygen into carbon dioxide, the carbon come from the burning fuel

Fan increase the speed of air, Air will do the rest.  Excess Temperature will desipate into air. Air will carry more heat In less time.

the water substance drowns the oxygen out of the "would be fire" in the hydrogen peroxide\n\nfire needs O2 to live

Fire requires fuel, heat, and energy to exist so as long as it gets started with enough heat (ie: match friction), and has enough to burn (wood, fuels), and oxygen as another source of fuel, it will burn.

Fire is simply a term that we use to describe a chemical reaction that results in the release of incandescent gas (usually due to the effects of the high temperature of the reaction on the reaction product (gas)).\n\nOrdinary wood fires are not hot enough to create plasma, the fourth state of matter. The sun is an incandescent ball of plasma, so it is technically not "fire" although it may appear to be so. A burning match, while hot, is not nearly hot enough to convert gas into plasma.

fire is the heat let off by oxidation (bonding oxygen to other compounds) since the oxygen in water is already bonded to hydrogen it can't be used in the oxidation of the fuel of the fire. water w/ it's high heat capacity absorbes a lot of energy  and also prevents oxygen from getting to the fuel.

Spray on coating or clad in fire protective material.\n\nNot sre what your question actally is though :-)

If we answer that question, we will be quite a bit closer to answering the actual question here.\n\nWhen you have combustion, such as a match, what happens is that oxygen gets consumed, and other gases (such as carbon dioxide) get produced. In addition, of course, energy is liberated in the form of heat and light. The produced gases are hotter than the environment due to the generated energy, and they expand, as heated gases do. Then, of course, since their density is lower than the surrounding atmosphere, the gas tends to rise. This has two effects. First, while it moves up, it carries energy with it, thus the flame ends up pointing "up". Second, since the products of combustion move up, they make more oxygen available to make the flame continue to burn.

Flame, as opposed to fire, is primarily a plasma, which means that it's a gas in a an excited state. As a substance burns the heat produced causes it to vapourise. As a result solids and liquids don't strictly burn, rather it is the gas evaporating off them that burns. \n\nAs the gas starts to burn it starts to break down into chemically smaller components. As a reuslt of the breakdown the electrons within the gas components become excited and unstable. As they collapse into more chemically stable forms like carbon dioxide the gases lose that excited state in the form of radiated energy that we detect as light and heat. \n\nAs a rsult we see flame as a bright light, sense it as being hot and see it flicker and waver, since it exists as a gas in air. It also only exists for a relatively short distance above the burning substance because the chemcially excited form only exists for a relatively breif period.

dont know about q1\n\nQ2 They push the heat out at the floor because the coler air is at the bottom of the floor and since hot air rises then then the hot air will circulate more by rising through the cooler air and warming it up as opposed to being near the ceiling where the hot air would just stay near the ceiling.\n\nQ3 The smoke is usually heated and composed alot of carbon monoxide. The heated smoke will rise as it is warmer than the cooler air around it, once it cools down to the temperature around it than it will usually fall back down since carbon monoxide is heavier than air and that it will also combine with other elements in the air.\n\nQ4 A continuous hot water system works better because the the hot water is circulated throughout whatever system it is heating, such as air or other water then return back to the heater (furnace) not cooled completely and still retaining some of the heat it originally had and since it is already warm it takes less energy and time to heat it back up to its original temperature.

Aw. Still not fast enough. Two people beat me!\n\nWhen you burn gas of any type you will produce water vapor as part of the chemical reaction. The water vapor condenses as it cools and dribbles out when the tail pipe is lower than the rest of the pipe.

Oxygen is what fuels fire, but when we blow out a candle there is so much force in your breath that the flame is blown out otherwise it would only make it bigger. Oxygen is highly flammable, carbon-dioxide is a fire suppressant.

When something burns the vapor given of by the reaction between the fuel, oxygen and heat is what is actually burning.  The flame goes up because this vapor is less dense than the surrounding air.

A regular fire, like in a fireplace or campfire, consists of burning organic material such as wood or other plant material which is mainly made from Carbon, with hydrogen. When the wood burns, the carbon combines with oxygen. It releases a lot of energy that was stored in the chemical bonds of the wood.\n\nAs the wood burns, some of it is very hot, and other parts are not yet hot, are heating up or are being burned loose and carried away by the currents of air moving between the sticks of wood. So the fire is giving off Carbon dioxide, partially burned fractions of the wood, hot ut unburned pieces of the wood, and pieces of wood that are hardly hot at all. In some cases, there will be carbon atoms that are hot but they were in a part of the fire where all the oxygen had been used up, so those atoms may be hot but not burned. \n\nAll these various materials can be glowing with heat. Because they are all different temperatures, they have different colors.  It might be easier to see this in a candle flame than in a fire. \n\nIf you look at the candle flame you see a part where the actual combustion is taking place - that is, where there are carbon atoms actually in the process of combining with oxygen. That area might be quite hot and have no color at all. But there is probably an area above that which is yellow - that's probably unburned carbon atoms which are glowing from heat, but they are cooling off. As they cool off you see an area where they are no longer yellow. If you put a cool piece of glass or metal in that part of the flame, it will collect a coating of the unburned carbon atoms, what we call 'soot'.\n\nPeople have been looking at candles for a long time, trying to understand how the burning process works. So I think you could go all the way back to Michael Faraday in the mid 1800s for a book on candles and flames, and some updated versions on the web.

In a fire, Oxygen is not the fuel, it is the oxidizer.  Depending upon what is burning, the fuel could be any number of things.\nOxygen does not burn, but is required for combustion.\n\nIn order for something to burn, 3 things are necessary,\n-Fuel\n-An oxidizer (Oxygen)\n-[activation] Energy\n\nUnless these 3 things are present, the object in question will not burn.\nIf we assume fuel and Oxidizer are plentiful, then the only thing left which will keep something from burning is that extra bit of energy needed to set off the reaction.  After one gets a fire going, usually, this energy is provided by the excess heat the fire generates, but it needs to be supplied initially by some form (for example, lighting a match to start light a candle).\nIf one were to take away the fire's ability to provide its own activation energy, it would go out unless supplemented by some outside source.\n\nWhen a gust of wind blow out a fire, it is blowing away the energy the fire needs to burn, it is cooling it off too much for it to continue burning.
