Why incense stick fragrance only spread when ignited?
When an incense stick is ignited, the heat causes the aromatic compounds in the incense to vaporize and release into the air as fragrant smoke. This smoke carries the fragrance molecules, spreading the scent throughout the room. When the incense stick is not ignited, the aromatic compounds remain solid and do not vaporize, so the fragrance does not spread.
When an incense stick is lighted the smell is felt throughout the room. Why does this happen?

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.
