Question

When a gas changes to solid without going into the liquid phase, the process is called

  1. Deposition
  2. De-sublimation
  3. Condensation
  4. Both a and b

hintHint:

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.
