Question

Explain how camphor disappears without leaving any residue.

Answer 1

Camphor:

• Camphor is a transparent solid with a chemical formula ${\mathrm{C}}_{10}{\mathrm{H}}_{16}\mathrm{O}$.
• The molecules of camphor are held together by a very weak force of attraction.
• At a very moderate temperature, the molecules of camphor spread rapidly and get sublimated.

So, camphor sublimates to gas at a very low temperature and does not leave any residue.
