Process+Skills+MCQ17

Hi all,

This is the website with the experiment found in the MCQ17. It is important to understand the set-up that is used to show the process of sublimation. ** Sublimation is the change of state from solid to gaseous without going through the liquid state. **So in this experiment, the solid air freshener becomes vapour and when the vapour comes in contact with the cooler underside surface of the beaker containing ice, ** deposition (the vapour becomes solid again) **takes place. Do take note of other substances that sublime or go through this process besides the solid air freshener. One common example is the use of dry ice during wedding dinners.
