• Boiling of water

• Ice turning into vapor

• Condensation of steam

Under what conditions can iodine undergo sublimation?

• High humidity

• Specific conditions

• Low temperature

• High pressure

Which process is the opposite of sublimation?

• Melting

• Freezing

• Evaporation

• Deposition
