Combustion is a Chemical Process
Combustion is a chemical process in which a substance reacts with oxygen to produce heat and light. In this process, the substance is called the fuel, and the oxygen is called the oxidizer. The reaction between the fuel and the oxidizer releases energy in the form of heat and light.
Chemical Reaction
Combustion is a chemical reaction that involves the transfer of electrons between the fuel and the oxidizer. The fuel is oxidized, and the oxidizer is reduced. This process releases energy in the form of heat and light. For example, when we burn wood, the carbon in the wood reacts with oxygen in the air to produce carbon dioxide and water vapor. This process releases energy in the form of heat and light.
Physical Changes
While combustion is primarily a chemical process, it can also involve physical changes. For example, when we burn wood, the wood undergoes physical changes as it is transformed into ash and smoke. These physical changes are a result of the chemical reaction between the wood and oxygen.
Conclusion
In conclusion, combustion is a chemical process that involves the transfer of electrons between the fuel and the oxidizer. This process releases energy in the form of heat and light. While it can also involve physical changes, the primary nature of combustion is chemical.
