How does a flame burn?

Answer 1

That is actually a very interesting question. When something like wood starts to burn, it heats the wood itself, and this heat is enough to vapourize many of flammable compounds that makeup wood itself, organic molecules such as ketones, aldehydes, hydrocarbons. Once these molecules escape from the burning piece of wood and encounter oxygen, but as the piece of wood gets hotter and volatile compounds are released faster, the oxygen immediately around the burning wood is consumed and the flammable molecules has to travel further away before it bumps into a oxygen molecule and combust.

Answer 2

A flame burns by a chemical reaction called combustion, where fuel combines with oxygen to produce heat and light. The fuel source typically consists of hydrocarbons and the oxygen comes from the surrounding air. The heat generated sustains the combustion process, while the light is a byproduct of the reaction.

Answer 3

A fire is created by friction andit lights up because the oxogyn gives the fire life to burn on.

Answer 4

A flame is the result of a combustion.
