Chemical Reaction Of Wood Burning
Co-ordinate to Greek mythology, the gods took fire away from people. And then a hero named Prometheus stole it back. Every bit punishment, the gods chained the thief to a stone, where an eagle fed on his liver. Every night, his liver grew back. And each day, the eagle returned. Like other myths, the Prometheus story offered ane caption for the origins of fire. It doesn't, however, offering clues to why things fire. That'south what scientific discipline is for.
Some ancient Greeks believed that fire was a basic element of the universe — one that gave rise to other elements, like world, water and air. (Aether, that stuff the ancients idea stars were made of, was later added to the list of elements by the philosopher Aristotle.)
At present scientists use the word "chemical element" to draw the most basic types of matter. Burn down does not authorize.
A fire's colorful flame results from a chemical reaction known every bit combustion. During combustion, atoms rearrange themselves irreversibly. In other words, when something burns, there's no un-burning it.
Burn also is a glowing reminder of the oxygen that pervades our world. Any flame requires three ingredients: oxygen, fuel and rut. Lacking even one, a burn down won't burn. As an ingredient of air, oxygen is commonly the easiest to find. (On planets such as Venus and Mars, with atmospheres containing far less oxygen, fires would be hard to start.) Oxygen's role is to combine with the fuel.
Any number of sources may supply heat. When lighting a match, friction between the match's head and the surface against which it's struck releases enough oestrus to ignite the coated head. In the Avalanche Burn, lightning delivered the heat.
Fuel is what burns. Nearly anything can burn down, but some fuels accept a far college wink point — the temperature at which they'll ignite — than others.
People experience oestrus every bit warmth on the pare. Non atoms. The building blocks of all materials, atoms only become fidgety as they warm. They initially vibrate. And so, as they warm even more than, they start dancing, faster and faster. Apply enough heat, and atoms will break the bonds linking them together.
Woods, for example, contains molecules made from jump atoms of carbon, hydrogen and oxygen (and smaller amounts of other elements). When wood gets hot enough — such as when lightning hits or a log is tossed on an already burning fire — those bonds break. The process, chosen pyrolysis, releases atoms and free energy.
Unbound atoms course a hot gas, mingling with oxygen atoms in the air. This glowing gas — and not the fuel itself — produces the spooky bluish light that appears at the base of a flame.
But the atoms don't stay single long: They quickly bail with oxygen in the air in a process called oxidation. When carbon bonds with oxygen, it produces carbon dioxide — a colorless gas. When hydrogen bonds with oxygen, information technology produces h2o vapor — even as the wood burns.
Fires burn only when all that atomic shuffling releases enough energy to keep the oxidation going in a sustained chain reaction. More than atoms released from the fuel combine with nearby oxygen. That releases more energy, which releases more than atoms. This heats the oxygen — and then on.
The orange and yellow colors in a flame appear when extra, complimentary-floating carbon atoms get hot and begin to glow. (These carbon atoms also make upwardly the thick black soot that forms on grilled burgers or the lesser of a pot heated over a burn.)
