Answer:

Just to retire this question....

Explanation:

...typically matter goes from a condensed phase, a solid or liquid, when heated, to a gas...

#"Solid"+Delta_1stackrel("melting")rarr"Liquid"+Delta_2stackrel("boiling")rarr"Gas"#

And the reverse applies when the matter is cooled....

#"Gas"stackrel("condensation")rarr"Liquid"+Delta_2stackrel("fusion")rarr"Solid"+Delta_1#
