When iodine is heated to 114°C, it sublimes directly from a solid into a gas. Explain, in terms of forces, the change that occur to the structure of iodine as it sublimes

The process of transition of a substance directly from its solid phase to gaseous phase without going through the liquid state is called sublimation. Iodine crystals, dry ice, naphthalene (moth balls) and arsenic tend to sublimate. ... You can send something frozen you can pack it in dry ice

Hey friend,
I hope it helps you!!!
They sublime because though there are covalent bonds within the molecule holding two iodine atoms together, only van der Waal's forces exist between the iodine molecules. Van der Waal's forces are very weak interactions between molecules of a substance hence the iodine molecules can escape from the solid structure
