Answer and Explanation:
Sublimation is a process of converting a substance from solid state to gaseous state without the formation of liquid at constant temperature.
Solid \rightleftharpoons GasSolid⇌Gas
A substance which undergoes sublimation is called as sublimating substance.
As camphor has weak inter molecular forces of attraction between its molecules, it directly sublimes into gaseous state without leaving any residue and is called as a sublimating substance.
