Hint: In this question, you should know the properties of a sublimate like camphor as an example, to identify the answer. Try to recall the basic definition, then you will definitely get an idea.
Complete step by step answer:
> Ammonium chloride on heating directly converts into vapour. This process is called sublimation. In contrast to this, common salt is not sublime.
So from a mixture, containing ammonium chloride and common salt, ammonium chloride can be easily separated by the process of sublimation. On heating ammonium chloride converts into vapour leaving behind the non-volatile component, Salt. On cooling the vapour of ammonium chloride changes into solid.
> In the process of sublimation, the compound which converts from solid to directly in the vapour is called sublimate. Hence, on heating ammonium chloride, it gets converted into white vapours. The gaseous form of ammonium chloride can be cooled easily to get a pure solid.
Therefore, we can conclude that the correct option is C.
Note: We can separate the mixture of sand and ammonium chloride by the method of sublimation.As ammonium chloride is a sublimable substance whereas the sand is not. So ammonium chloride will sublimate and the sand will remain left behind, thus we get both the components separately.
