What does a fire result from?
Correct Answer
B. A chemical reaction when oxygen combines with a fuel to produce heat
Explanation
A fire results from a chemical reaction when oxygen combines with a fuel to produce heat. This reaction is known as combustion. Combustion occurs when there is a sufficient amount of fuel, oxygen, and heat present. The fuel can be any combustible material such as wood, paper, or gasoline. Oxygen is necessary for the combustion process as it acts as an oxidizing agent. When the fuel and oxygen combine, they undergo a chemical reaction that releases heat and light energy, resulting in a fire.
