Fire burns because of the chemical reaction known as combustion, which involves the rapid combination of oxygen with a fuel source, releasing heat and light energy in the process. This process can be explained logically through the principles of chemistry and physics. When a fuel, such as wood or gas, comes into contact with oxygen in the presence of sufficient heat, it undergoes oxidation, breaking down the fuel molecules and releasing energy in the form of heat. The heat generated further sustains the combustion process, creating a self-sustaining chain reaction. Therefore, the phenomenon of fire burning can be understood through the application of scientific principles and logical reasoning, making it a matter of empirical observation and scientific analysis, rather than mere conjecture or speculation.
