What is fire.
What is fire?
Fire is the visible effect of the process of combustion – a special type of chemical reaction.
Why does fire burn your skin
It occurs between oxygen in the air and some sort of fuel. The products from the chemical reaction are completely different from the starting material.
The fuel must be heated to its ignition temperature for combustion to occur.
The reaction will keep going as long as there is enough heat, fuel and oxygen. This is known as the fire triangle.
Combustion is when fuel reacts with oxygen to release heat energy.
Fire chemical nameCombustion can be slow or fast depending on the amount of oxygen available. Combustion that results in a flame is very fast and is called burning. Combustion can only occur between gases.
Chemical reaction in the combustion process
Fuels can be solids, liquids or gases.
During the chemical reaction that produces fire, fuel is heated to such an extent that (if not already a gas) it releases gases from its surface.
Only gases can react in combustion. Gases are made up of molecules (groups of atoms).
When these gases are hot enough, the molecules in the gases b
