Interpretation:
The property a solid must have to sublime is to be explained.
Concept Introduction :
Sublimation is the process by which a substance transforms from a solid to a vapor without first entering the liquid state.
Answer to Problem 25LC
Solids having vapor pressures above atmospheric pressure at or close to room temperature sublimate.
Explanation of Solution
A solid must have a higher-than-normal vapor pressure, or weak intermolecular attractions, for sublimation to take place. This is typically true for solids with sphere- or cylinder-shaped molecules. Substances turn into vapor when their vapor pressure becomes equal to more than the atmospheric temperature. Thus, the solids having vapor pressures above atmospheric pressure at or close to room temperature sublimate.
