RankGuru · Accepted Answer

**Sublimation** is a physical process where a substance changes directly from a **solid to a gaseous state** without passing through the liquid phase upon heating.
- **Application**: Useful for purifying solids that possess a high vapor pressure below their melting point.
- **Examples**: **Naphthalene, Anthracene, Benzoic acid, Camphor, and Iodine**.
- Non-sublimable solid impurities are left behind in the heating vessel, while the sublimed vapors are condensed back to pure solid on a cold surface.
