Explain why understanding the process of combustion requires using an atomic model of mass and not a continuous one.

Combustion is a rapid exothermic chemical reaction between oxygen, O₂, and a substance which is known as the fuel that is initiated by an ignition (heat) source to produce carbon dioxide and water vapor other oxides and combustion products

With the continuous model, which is the model seen with the naked eye, that have uniform parts, the combustion of coal that produces no flammable vapors and hence no flame, the combustion of hydrogen gas which is nearly colorless and the combustion of gasoline that produces a bright flame, burns without flame will be taken as different processes
