Question

camphor disappears without leaving and residue why.​

Answer 1

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.

Answer 2

Answer:

camphor is a sublime substance. it get transformed from solid to directly gaseous state without passing from liquid state. when burnt or kept in open it get sublimated and the vapours go to the atmosphere without leaving any residue.
