Final answer:
The behavior of fires is influenced by the fuel source, oxygen availability, and heat.
Step-by-step explanation:
The behavior of fires is influenced by several factors including the fuel source, oxygen availability, and heat. Fuel source refers to the material that is burning, such as wood, paper, or gas. Different fuel sources have different properties and burn at different rates. Oxygen availability is necessary for the combustion process to occur. Oxygen fuels the fire and allows it to sustain and grow. Heat is the energy needed to start and maintain a fire. It can come from various sources, such as a spark, a chemical reaction, or even friction.
