👉 A burning fluid, also known as a flame or combustion product, is a substance formed when a material undergoes rapid oxidation in the presence of oxygen. This process releases energy in the form of heat and light, creating a visible flame. The fluid state refers to the fact that it exists as a liquid or gas at room temperature, but it transitions into a gaseous state when ignited. The burning fluid's composition depends on the original material, but it typically consists of atomic and molecular fragments that readily react with oxygen, producing the characteristic glow and warmth of a flame.
