Answer: Sublimation
Explanation:
Sublimation : It is a process in which a solid directly changes to gaseous phase by providing heat.
Freezing is a process in which a liquid changes into solid phase when allowed to cool.
Condensation is a process in which a gas changes into liquid phase when allowed to cool.
Deposition is a process in which a gas deposits as solid phase when allowed to cool.
Thus change of state where energy is absorbed is sublimation.
