"Take some ammonium chloride salt in a china dish. Crush the salt and cover the dish with a funnel, as shown in the figure. Plug the stem of the funnel using some cotton. After this, start heating the dish slowly using a burner.
Result of the activity
Upon heating, ammonium chloride will vapourise without transforming into its liquid form
(sublimation).
Later, the vapours will get cooled on the walls of the funnel and will directly convert into solid ammonium chloride
(deposition)
Q.
Explain why in this activity camphor turns from vapour to solid state and settle at the walls of funnel.
