Answer: vaporization
Explanation: Condensation is a physical change involving phase transition from gaseous to liquid phase when energy is withdrawn.
Example of condensation: [tex]H_2O(g)\rightarrow H_2O(l}[/tex]
Thus the reverse of condensation is a process where phase changes from liquid to gas.
Thus the reverse of condensation is vaporization where particles change from liquid to gaseous phase when energy is supplied.
Example of vaporization: [tex]H_2O(l)\rightarrow H_2O(g)[/tex]
