Question

Define sublimation and sublimate. Give one example of sublimation.

Answer 1

Sublimation: The process of conversion of a substance from the solid state into the gaseous state on heating directly without converting into a liquid state.

• Example: Camphor, Naphthalene.
• $\mathrm{Camphor}\left(\mathrm{s}\right)\underset{\mathrm{Cool}}{\overset{\mathrm{Heat}}{\rightleftarrows }}\mathrm{Camphor}\left(\mathrm{g}\right)$

Sublimate: The solid obtained after the condensation of the vapours once they have cooled is called sublimate.

• The solid camphor obtained from the cooling of camphor vapours is called as sublimate in the above example.
