Whar is a Fire? and in which catagory would u like to put fire 1-liquid 2-gas 3-solid or another?

Question

Fire is form of energy

Answer 1

Your asking what state of matter is fire.

The answer is none of the above. Fire is a chemical reaction. Not a chemical species. It is not a form of energy either. It is a label we give to a particular chemical reaction. One that always releases energy.

That energy could be in multiple forms such as infrared radiation for example. Or visible light. So I suppose you could ask, since radiation is a form of energy and energy and mass are equivalent, what form of matter is radiation?

Well, let's take a step back for a second...

first ignore E = Mc^2 and use the corrected for of the equation for mass that includes velocity terms (ie the relativistic form). where M = rest mass.

E = M x c^2 / (1-v^2/c^2)^.5

since the velocity of a photon of light is c ( it travels at the speed of light) E goes to infinity if M is positive.

simplifying the above equation gives...
E^2 = c^2p^2 + m^2 c^4

for m = 0

E = cp where p is it's momentum = h x frequency / c
h, by the way, is plancks constant

in other words, the energy of a particle of light depends on it's momentum (or frequency or wavelength if you wish) and not on rest mass. ie. light has no rest mass and you should not be trying to use the equation e = mc^2 to calculate it. therefore it doesn't fall into one of your states of matter.

Answer 2

If by fire you mean the flame, the usually red-glowing stuff, then the answer is somewhere between gas and "another". The chemical reaction called burning (combustion), which is essentially rapid oxidation, produces large amounts of energy. This extra energy is evident because fire is hot. This extra energy causes electrons in the atoms of gases surrounding the burning substance to jump to higher electron layers of the atom, or even to leave the atoms, leaving behind ions. When you have electrons and ions, it would be plasma, a state of matter - one of the "another". If electrons just jump to higher layers it would still be gas.
Anyway, as the electrons return to their original places (or other electrons take up those spaces), they release photons of light - that you see as flame.
That's how I understand it.

Answer 3

Flames themselves are an incandescent gas or aerosol that you can see because their constituent materials are at a temperature that causes them to emit visible light. Heat is energy, fire is what happens during combustion. It's a tricky question because the flame is composed of particles that are oxidizing at a high temperature. I don't think fire is considered to be a state of matter because it is a chemical reaction, so it would be inappropriate to call it a gas, liquid etc.

Answer 4

Fire is the combustion reaction between a fuel and oxygen and giving out heat energy.
All matter contains energy.

*...Class A.. Combustible solid materials such as paper, wood, cardboard, and most plastics.

*...Class B: Flammable or combustible vapours of all hydrocarbon liquids such as crude oil, gasoline, kerosene, grease, waxes and lube oils, also cooking oils.. etc.

*...Class C: Electrical equipment, such as appliances, wiring, circuit breakers and outlets. Never use water to extinguish class 'C' fires - the risk of electrical shock is far too great!

*...Class D: Combustible metals, such as magnesium, titanium, potassium and sodium.

Answer 5

fireplace is a gasoline that outcomes from a chemical change. that's, a strong, liquid or gasoline will integrate with oxygen and launch means, and contained in the approach turns right into a clean gasoline with a countless chemical makeup.

Answer 6

technically fire (the actual flames) are photons caused by the combustion of some material in the presence of oxygen

Answer 7

1 fire is nice 2 liquid is good too. solid is ok

Answer 8

it would fall under none of the categories as it is somewhat of an observed phenomena during combustion of a liquid, gas or solid.
It is a form of energy as you said.

Answer 9

4 - None of the above

Energy is not matter, matter is not energy.
