Question

Give reason for camphor disappears without leaving any Residue

Answer 1

because camphor is sublime , it sublimate without leaving any solid by the process of sublimation

Answer 2

Camphor disappears after some time as its surface gains kinetic energy and directly gets converted into gas. The process of converting directly into gaseous form and not in a liquid state is termed as sublimation. Hence, when camphor is given fire, it gets converted into gas and disappears, without leaving any residue.
