you can bet that a change from one physical state to a LESS orderly state will require an input of energy (endothermic)
so let's pick II. vaporization and III. sublimation
When you get a good response,
please consider giving a best answer.
This is the only reward we get.

An endothermic process is one which absorbs heat, as opposed to an exothermic process which gives off heat.
Exothermic: deposition, freezing and condensation
Endothermic: sublimation, melting, and vaporization
