    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

    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.
