Why As soon as we light an incense stick the fragrance spreads?

As soon as we light an incense stick, the combustion of the aromatic materials within it produces smoke that carries the fragrance. This smoke is composed of tiny particles that disperse into the air, allowing the scent to spread quickly. Additionally, the heat from the burning stick facilitates the release of volatile compounds, enhancing the fragrance's diffusion in the surrounding environment. Thus, the combination of smoke and heat accounts for the rapid spread of the incense's aroma.
