Which term is described as the substance that provides the fuel for a fire?

• A. Oxygen
• B. Air
• C. Fuel
• D. Heat

Answer: (C)

Fuel is the substance that provides the energy for a fire by burning. In fires, three elements come into play: heat to reach ignition, oxygen to support the chemical reaction, and the fuel itself to burn. The term describes the material that actually undergoes combustion, releasing energy—examples include wood, gasoline, and paper. Oxygen is the oxidizer, not the fuel; heat is the energy input that starts and sustains combustion; air is the mixture that carries oxygen, not the combustible material. So the substance described as providing the energy for the fire is the fuel.
