Question

why do the fragrance spreads quickly in the room when the incense stick is lit?Is it any relation for this to temperature​

Answer 1

Answer:

When we light an incense stick (which is also called as agarbatti), in a corner of our room, its fragrance spreads in the whole room rapidly. The fragrance of burning incense stick spreads all around due to the diffusion of its smoke into the air. The smell of perfume spreads due to the diffusion of perfume vapours into air.
