👉 Phlogiston, also known as carbon dioxide or methane, is a gaseous substance that is released during combustion. It is one of the key components in the combustion process and plays a crucial role in many industrial processes. During combustion, fuel particles are ignited by heat and oxygen, and this reaction produces a large amount of heat and gas. Carbon dioxide (CO2) and methane (CH4) are two of the most common gases that can be produced during combustion. The term "ph
