What is FIRE??

Question

(other than a form of energy)

Answer 1

Fire is the result of a unclean combustion reaction. In which molecules are broken down (via combustion, due to added heat or other catalyst), and combined with O2, to create CO2 and H20 + other unclean parts (smoke). The heat that results excites the gas molecules that are flowing out of the exothermic reaction. These excited molecules refact different colors than at their normal state. Different color flames represent different molecules at different temperatures. That's why we can tell what is being burned by studying the color of the flame.
More to the point... Fire is the visible light that appears from excited molecules due to the energy released in a combustion reaction.

Answer 2

Burning is a chemical reaction and fire is the manifestation of that reaction. In order to have a fire you need 3 thing- fuel, heat, and oxygen. Remove any one of the three and you'll be with out fire. Think about lighting a camp fire. In the woods (oxygen) you stack up a little pile of dry wood (fuel), and you light a match (heat) to then start the chemical reaction. The reaction will last until the fuel (wood) is gone unless you add more fuel to continue the chemical reaction.

Answer 3

That is all it is,

The whole E=mc2 thing....

E= the amount of energy in an object
m=the mass of the object
c2 = the only true constant, the speed of light, squared

So, fire is that energy being released in many forms, heat, light, sound. when something cannot burn any more, thats when you start talking about splitting atoms

Answer 4

Fire, reaction involving fuel and oxygen that produces heat and light. Early humans used fire to warm themselves, cook food, and frighten away predators. Sitting around a fire may have helped unite and strengthen family groups and speed the evolution of early society. Fire enabled our human ancestors to travel out of warm, equatorial regions and, eventually, spread throughout the world. But fire also posed great risks and challenges to early people, including the threat of burns, the challenge of controlling fire, the greater challenge of starting a fire, and the threat of wildfires.

Answer 5

Fire is a form of energy that given off during enormous friction.

Answer 6

when something is burned electrons absorbs heat , thier energy increases and must jump on another level of energy(higher energy) but this state is unstable . electrons tend to come back privious level and give off energy . this energy is fire.

Answer 7

you cant define fire other than form of energy
it is an energy bunch which continuously radiates light
it is a dynamic equillibrium between burning of wax of candle and turning into smoke

Answer 8

Fire is an oxidation reation where energy is released (heat and light). Exothermic, since more energy is released than went in. Rusting is an endothermic oxidation reaction.

Answer 9

Fire is a natural component (energy) and may cause radical changes when there's a contact with other materials, structures or components

Answer 10

It is a popular form of self-abuse.
