Here’s a explanation:
Sublimation
- Sublimation is the direct change of a substance from solid to gas without passing through the liquid state.
Examples of Substances that Sublime
- Dry ice (solid CO₂) – turns directly into carbon dioxide gas.
- Iodine crystals – produce violet vapor.
- Naphthalene – used in mothballs.
- Camphor – often used in medicinal applications.
Key Idea:
- Sublimation occurs when vapor pressure of the solid is high enough at a given temperature, so the solid goes straight to gas.
In short: Sublimation = solid → gas directly, and common examples include dry ice, iodine, naphthalene, and camphor.
