I think it's sublimation. Not too sure, might wanna check that out!

eg Iodine
Reply:It is definitely 'Sublimation'.





The process by which solids are transformed directly to the vapor state without passing through the liquid phase. Sublimation is of considerable importance in the purification of certain substances such as iodine, naphthalene, and sulfur.





Sublimation is a universal phenomenon exhibited by all solids at temperatures below their triple points. For example, it is a common experience to observe the disappearance of snow from the ground even though the temperature is below the freezing point and liquid water is never present. The rate of disappearance is low, of course, because the vapor pressure of ice is low below its triple point. Sublimation is a scientifically and technically useful phenomenon, therefore, only when the vapor pressure of the solid phase is high enough for the rate of vaporization to be rapid.
Reply:The accepted term is 'sublimation'. Probably the best known substance with no liquid state at standard pressure is carbon dioxide; this is known as 'dry ice' when frozen and vapourises directly. It used to be used to generate smoke effects in theatres until safer alternatives were developed.
Reply:Sublimination, imagine how dry ice creates fog liike gas
Reply:LOL, I made up a song for this one: "Sublimation lack of liquidation, sublimation a game we like to play...." LoL its and old song, my mom taught me.....
Reply:sublimation as previously told
Reply:It's called "Sublimation".





(Opposite, from Gas to Solid without liquid phase is called "Deposition").
