What the particle theory says about sublimation?

The particle theory explains sublimation as the process where solid particles gain enough energy to overcome their intermolecular forces and transition directly into the gas phase without becoming a liquid first. In this phase change, the particles move from a closely packed arrangement to a more dispersed state, resulting in an increase in energy and movement. Sublimation typically occurs in substances with weaker intermolecular forces, such as dry ice (solid carbon dioxide) or iodine. This transition can be influenced by temperature and pressure conditions.
