* Exothermic: Combustion reactions release heat energy into the surroundings, making them feel hot. This is why fire is associated with heat.
* Rapid Oxidation: They involve the rapid reaction between a substance (the fuel) and an oxidant, typically oxygen, to produce heat and light.
* Production of Light: Combustion often produces a visible flame, which is the glowing hot gas resulting from the reaction.
* Formation of Products: The products of combustion depend on the fuel and the availability of oxygen. Common products include carbon dioxide (CO₂), water (H₂O), and ash.
* Requires Activation Energy: Combustion needs an initial input of energy (like a spark or flame) to start the reaction.
Here's a simple example:
* Fuel: Wood
* Oxidant: Oxygen (from the air)
* Products: Carbon dioxide, water, ash
* Energy Release: Heat and light (fire)
