What is...........?

Question

What is fire? I mean cuz it isnt a solid object you cant touch and feel...I mean you can feel the heat comming off of it...Another thing is, is that when you blow on it the flame goes out...But if its just like embers and no fire and then you blow on it if you blow on it hard enough the fire starts again? Why is that? Cuz I mean your doing the EXACT same thing..But you get different results...

Answer 1

What we call fire is actually an ongoing chemical reaction. The chemical reaction produces heat, light and ash (in simple terms). We see & feel the light & heat and call that fire. The reaction can be one that occurs very rapidly, we call that an explosion. Or it could occur more slowly, like the way charcoal burns. But generally we call fire the reaction that proceeds fast enough to cause flames but not so fast as to create a pressure wave.

Answer 2

You see fire is not matter. Matter is anything that occupies space and has mass. So three forms of matter is solid, liquid gas.
Fire is a chemical reaction in which it is a visible, tangible side effect of matter changing form.
Fire comes from a chemical reaction between oxygen and fuel.
Fire start when the fuel's ignition temperature is met, meaning the fuel need to be heated.
So for your question when you blow the flame, you just gave it too much oxygen to it (oxygen from the surrounding because you blow carbon dioxide and not oxygen) that it cannot hold but when it is in ember form it, since it is already hot it need a lot of oxygen to start the fire.
just like an event of fire when the season is windy the fire gets stronger and can spread quicker, because you feed it oxygen. The balance between the fuel and oxygen consumption must be met to produce an equal amount of fire.

Answer 3

Yes, fire IS matter! It's highly heated gas! It has mass, though it is nowhere near as dense as room temperature air around it, therefore it seems to always be rising...as it should.
When you heat a metal object, like a pin or knife (insert drug reference here) you can clearly see it glows bright red.
The reason you get burned is not because of the fire, it's because of the super-heated, glowing gas! (we call it fire)
Also, the reason you can blow out a match, but not an ember, is that the match hasn't got enough stored heat or material to re-ignite, whereas a large ember is already hot enough and has enough material to re-ignite.

Answer 4

Fire is actually a heat source as a fuel combusts. By blowing on embers you are suppling more oxygen to the embers casing them to combust into flames again.

Answer 5

fire is a conversion of chemical potential energy coming from the breakage of carbon-hydrogen bonds in whatever you're burning and reforming carbon and oxygen double bonds and hydrogen and oxygen single bonds. these bonds created release large amounts of heat and light energy, which we call fire. blowing on a fire pushes large amounts of carbon dioxide onto the flames, which makes it impossible for carbon to bond with oxygen and hydrogen to bond with oxygen, thus putting out the flame. blowing on embers pushes a large amount of carbon dioxide onto the area as well, but since embers don't need so much oxygen to continue smoldering, the amount of ambient oxygen being pushed into its vicinity is large enough to make it flare. you'll also notice that no flames pop up around embers until you stop blowing on it.

Answer 6

Fire is one of the elements of nature. There's earth, wind, fire and water.

When air blows on/over live embers it intensifies the heat, and a flame will reappear,, for a short period only unless fuel is added.

Answer 7

Fire is the combination of elements that when combined they produce heat and the release of the heat energy is in the form of a flame.

Answer 8

Fire is an explicit example of the fourth stage - the plasma.

Plasma is superheated gas, in state of excitation. Excitation is delivery of pure energy from the molecule or atom structure, while over-energized electrones "jump" from higher-energy levels to the lower-energy levels.

Such high energy makes the gas to glow, while releasing energy. We call it "fire".

Answer 9

when it is embers and you blow on it you are feeding it oxagen and that is why the fire starts agian. fire feed on oxagen

Answer 10

Fire is superheated gas due to combustion.
