Question

.. An agarbatii stick does not smell. When it is not lighted. When it is lighted, the smell is felt throughout the room. Explain the phenomenon.​

Answer 1

Answer:

Diffusion

Explanation:

Before lighting the components of the agarbatti exist in solid state in which diffusion rate is minimal due to tight intermolecular forces of attraction.

However on lighting, the components enter gaseous state, in which there is maximum diffusion due to very weak forces of attraction and random movement.

So the smell disperses throughout the room quickly
