Undergo combustion is a term used to describe the process of burning. It is a chemical reaction that involves the combination of oxygen with a fuel, such as wood, coal, or natural gas, which produces heat and light. The heat produced from the combustion of these materials can be used to generate electricity, power engines, and provide warmth. In some cases, the combustion process can also produce toxic gases, such as carbon monoxide, which can be hazardous to human health.
