When opening a box if camphor it’s smell spreads all around. The conceptual reason for this is due to the diffusion. When the camphor is placed outside the air molecules will react with the camphor.
This will make the smell to spread in air. The molecules will break and the tightly held molecules will get diffused.
The loosen structure will make the smell of the camphor to spread in air and it will evaporate after a certain period of time.

I am mercury which rises up due to temp. increase and comes down if we shake it because of a Kink. Mercury thermometers cover a wide temperature range from −37 to 356 °C (−35 to 673 °F); the instrument's upper temperature range may be extended though the introduction of an inert gas such as nitrogen.
