1. Fuel: A combustible substance that can react with oxygen to produce heat and light. This could be anything from wood and paper to gasoline and natural gas.
2. Oxygen: A non-flammable gas that is essential for combustion. Oxygen is present in the air we breathe, and it is also the main component of oxidizers, such as hydrogen peroxide.
3. Heat: An external source of heat is needed to initiate combustion. This could be a spark, a flame, or even the heat of the sun.
When all three of these ingredients are present, combustion can occur. The fuel will react with the oxygen, releasing heat and light energy. This process will continue until the fuel is consumed, or until the heat source is removed.
Here's a more detailed explanation of what each component does in the process of combustion:
1. Fuel: The fuel provides the energy for the combustion reaction. When it comes into contact with oxygen and heat, the fuel's molecules break apart and release energy in the form of heat and light.
2. Oxygen: Oxygen is the oxidizing agent in the combustion reaction. It combines with the fuel molecules to form carbon dioxide and water vapor, releasing heat and light energy in the process.
3. Heat: Heat is the energy that initiates and sustains the combustion reaction. It provides the energy needed to break apart the fuel molecules and combine them with oxygen. The heat source can be external, such as a spark or a flame, or it can be generated by the combustion reaction itself.
For example, when you light a candle, the flame provides the initial heat needed to start the combustion reaction. The oxygen in the air reacts with the wax molecules in the candle, breaking them down and releasing energy in the form of heat and light. This process continues until the wax is consumed or the oxygen supply is cut off.
In general, for complete combustion to occur, there needs to be a sufficient amount of fuel, oxygen, and heat. The specific requirements can vary depending on the type of fuel being used.
