If water is H2O what is fire?

Answer 1

Water is a form of matter (hence the easily identifiable h2o). Fire is a combustion reaction: oxygen reacts with a fuel (wood, gasoline, etc.) that is brought to its ignition temperature.

Answer 2

Water is matter.
A molecule of water has the formula H2O as it contains one atom of oxygen and two molecules of hydrogen
Fire on the other hand is energy and is not made of matter. Hence you can't have a formula for fire.
Matter and energy are interconvertible though. But for it to be possible you require certain conditions.
Matter is converted to energy in nuclear reactions such as fusion and fission anhd to be able to convert energy into matter you require extremely high energy densities.
The mass-energy equivalence is given by Euinstein's famous equation E=mc2
And fire is definitely not hot gases
:)

Answer 3

Fire is heat, its energy. YOu have matter and energy. Water is matter, fire is energy.

Basically look at methane burning

CH4 + O2 = CO2 + H20 + energy(not balanced)

But you see a fire when this happens which is the energy word in that equation

Answer 4

fire is what happens when one thing is changing into another.

for example C + O2 = CO2 (Carbon and oxygen become Carbon Dioxide) Not the C the O2 or CO2 are fire, but the process of changing the two into the one is fire.

Answer 5

Energy

Answer 6

What is fire? Or 'what are flames?'
Flames are incandescent particles of partially combusted material floating away from the source of combustion and mingling with the air. They are a kind of glowing smoke really. (Plasma flames are even hotter, and are, as the name suggests, made of plasma- you see them around arc-welders).

Answer 7

the combustion of wood for example . .excite various inter-molecular links ..it accelerate molecular movement until broking them (if you to rub your hands.it heated)
the carbon C (for example) will be detached of wood. .its mixture with O2 of the air gives the CO (a toxic gas.. it's color is black) and
Residue like coal
then Fire is a rapid oxidation process that creates light, heat, and smoke
fire is a transitory stage of this transformation

Answer 8

All the answers r wrong above.All of us have studied 3 kinds of matter-solid, liquid n gas.There r 2 more states.One is plasma n the other I dont remember.Fire is an example of plasma state.

Answer 9

Well, H20 is a chemical whereas fire is a chemical reaction.

Answer 10

Hot gases.
