Question
Which process is used to purify the solids?
- Sublimation
- Condensation
- Deposition
- Freezing
Hint:
At freezing point, only pure solid crystals would be formed.
The correct answer is: Sublimation
- Sublimation is the process of conversion of a solid to a gas without converting to an intermediate liquid.
- Condensation is the process of conversion of water vapor in the air to liquid.
- A deposition is the phase transition process from solid to gas without converting to intermediate liquid.
- Freezing is the conversion of liquid to solid. The different liquid freezing point is different, at that particular point only the pure solid crystals would be formed.
