Answer 1

hi friend
here's your answer looking for

basically when we observe the incense stick that is burning, we can observe it smell from the several metres away.

the smoke of incense stick is the gaseous state of matter.
smoke of incense stick is gaseous sstate of matter has the larger intermolecular space and highest kinetic energy.

so because of the high kinetic energy its particle starts vibrating and move rapidly and reaches to our nose from the several metres away.

So, two factors that are responsible for this spirit of smell are:-

1). intermolecular space

2). higher kinetic energy in the particles
