Question

If 50 incense sticks are placed in a corner of a room, do we need to go close it in order to smell it? why?

Answer 1

no need to go near it because of the diffusion property of gases the smell travels all around the room. gases diffuse faster

Answer 2

yes we need to go closer .
bcuse as they are in solid form n its paricles have less diffusiion so it will not able to smeell it from a far dist but if we burn we can smell as gases have more intermolecular spaces n more diffusion.
