Question

Draw a labelled diagram to illustrate the process of sublimation of separation of ammonium chloride from a mixture of common salt and ammonium chloride.

Answer 1

When anything solid turns into a gas without first becoming liquid, that's sublimation

Answer 2

Sublimation:It is a process in which matter undergoes a phase transition directly from a solid to gaseous form, or vapor, without passing through the more common liquid phase between the two. We know that ammonium chloride changes directly from solid to gaseous state on heating.
