Question

Give one word for the following:

The solid was obtained after solidification of vapours of sublimable compound.

Answer 1

Sublimation

• The process in which a substance from solid-state directly turns into its vapour without changing into the liquid state on heating.
• The solid which undergoes sublimation is called sublime.
• Example: Iodine crystals are solid at room temperature $(25°\mathrm{C})$ and $1\mathrm{atm}$ pressure but on heating it convert into iodine vapour.

Deposition/ Desublimation:

• The process in which vapors directly turn into solid without changing into the liquid state on cooling.
• It is the reverse of sublimation.
• The solid obtained on cooling vapors is known as sublimate.
• Example: Iodine vapors directly change into iodine crystals on cooling.

The solid obtained after solidification of vapors of sublimable compound is sublimate.
