Well, #"boiling"# is the opposite process to #"condensation"#......

#"Liquid "stackrel("Boiling")rarr" Vapour"#;

#"Vapour "stackrel("Condensation")rarr" Liquid"#.

And a posh word for #"boiling"# is #"ebullition"# (the study of boiling point, and its use in analysis is called #"ebullioscopy"#).

And, #"melting"# is the opposite process to #"freezing"#......

And the transition solid to gas is #"sublimation"#....

#"Solid"# #stackrel("sublimation")rarr" Gas"#

#"Gas"# #stackrel("deposition")rarr" Solid"#

When a solid material is collected after sublimation (and deposition), the material (usually very pure) is called the #"sublimate"#.
