Fire is a chemical reaction.

Fire is a chemical reaction.

• A. False
• B. True
• C. Both
• D. Neither

Answer: (B)

Fire is a chemical reaction. Specifically, combustion is the rapid oxidation of a fuel in the presence of heat and oxygen, producing new substances such as carbon dioxide and water and releasing energy as heat and light. This involves breaking and forming chemical bonds, so it’s a chemical change, not just a physical one like melting or boiling. The flame can continue only while heat, fuel, and oxygen are present—the classic fire triangle. That’s why the statement is true: fire is a chemical reaction. The other options would imply it isn’t chemical or that the situation is unclear, which isn’t the case for combustion.
