Fire burning is fundamentally a chemical process.
Understanding Combustion
At its core, a fire is the result of a chemical reaction known as combustion. This reaction occurs when fuel and oxygen react with one another.
During combustion, the atoms within the fuel and oxygen molecules undergo a significant change: they rearrange themselves irreversibly. This rearrangement releases energy, which we perceive as heat and light – the fire itself.
While colour can be influenced by temperature, the chemical reactions involved are primarily responsible for the fire.
