The change from a solid to a gas without going through the liquid state is called sublimation. This process occurs when the temperature of a solid is raised to a point where its particles gain enough energy to break free from the intermolecular forces holding them in a fixed lattice structure. As a result, the solid particles transition directly into a gaseous state, bypassing the liquid phase.

Sublimation is commonly observed in substances that have a high vapor pressure, such as dry ice (solid carbon dioxide), camphor, and naphthalene. These substances can sublime at room temperature or slightly above, releasing their molecules directly into the air.

In natural environments, sublimation plays a significant role in the water cycle. It occurs when snow or ice on the Earth's surface transforms directly into water vapor, without melting into liquid water. This process contributes to the formation of clouds and atmospheric moisture.
