Combustion, also known as burning, is a chemical process involving rapid reaction between a substance with an oxidant, usually oxygen, to produce heat and light.

Here are key aspects of combustion:

• Exothermic Reaction: Combustion is an exothermic reaction, which means it releases energy in the form of heat and light.
• Fuel and Oxidant: Combustion requires a fuel (the substance being burned) and an oxidant (the substance that combines with the fuel). The most common oxidant is oxygen (O₂) in the air.
• Ignition Temperature: Combustion typically requires an ignition temperature to initiate the reaction. This is the minimum temperature to which the fuel must be heated to start self-sustained burning.
• Products of Combustion: The products of combustion vary depending on the substances involved, but common products include:
  • Carbon dioxide (CO₂)
  • Water (H₂O)
  • Heat
  • Light (in the form of a flame)
