- This property is utilized in mothballs, where naphthalene sublimes to repel moths and other insects.
- Other examples of sublimable substances include iodine and dry ice (solid carbon dioxide).
Additional Information
- Sublimation is a phase transition that occurs at specific conditions of temperature and pressure.
- It is an endothermic process where a substance absorbs heat to change its state.
- Sublimation is used in various industrial processes, such as freeze-drying and purification of substances.
- Understanding the properties of sublimable substances is crucial in applications like air fresheners and chemical synthesis.
