Question
When a gas changes to solid without going into the liquid phase, the process is called
- Deposition
- De-sublimation
- Condensation
- Both a and b
Hint:
Sublimation is the conversion of solids to gases without converting to liquid.
The correct answer is: Both a and b
- A deposition is a phase transition in which matter transitions directly from a gaseous state to a solid without passing through the intermediate liquid.
- Condensation is the conversion of water vapor in the air to liquid.
- De-sublimation is a similar phenomenon of deposition.
