With the help of a labeled diagram, describe in brief an activity to show sublimation of camphor

Sublimation of camphor:
Activity:

  1. Take some camphor. Crush it and put it in a china dish.
  2. Put an inverted funnel over the china dish.
  3. Put a cotton plug on the stem of the funnel, as shown in the diagram below.
  4. Now, heat the china dish slowly with the help of a Bunsen burner and observe.
  5. Camphor which is in the solid state on exposure to heat will directly change into the vapour state.
  6. The vapours on rising up in the funnel will start condensing and form crystals of caphor.
