Answer:

#"Sublimation..............."#

Explanation:

Sublimation involves the transition #"solid"# #rarr# #"gas"# WITHOUT the intermediacy of the liquid phase. At normal (atmospheric) pressure, a few substances sublime, most notably dry ice, whose sublimation temperature is #-78# #""^@C#.

The reverse of this transition is called #"deposition"#.
