It is the chemical reactions that occurs between substances when materials burn
Answer (1)
Combustion is a chemical reaction when materials burn. This is when a substance reacts with oxygen from the air and produces heat and light. Most of the time, it also releases gases like carbon dioxide and water vapor. Combustion usually happens with things that have carbon, like wood, paper, or fuel. What makes it a chemical reaction is that the original materials change into new substances, and you can't get them back to how they were before.
