Question

camphor disappears without leaving any residue. explain

Answer 1

CAMPHOR IS A SUBLIMATING SUBSTANCE .
IT DISAPPEARS WITHOUT LEAVING ANY RESIDUE DUE TO THE PROCESS OF SUBLIMATION THAT IS THE CONVERSION OF SOLID INTO GAS WITHOUT THE INVOLVEMENT OF THE STATE OF LIQUID...THEREFORE CAMPHOR VAPORISES WITHOUT LEAVING ANY RESIDUE BEHIND.....

Answer 2

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.

$Solid \rightleftharpoons Gas$

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.
