hope it will help you....

Answer 2

 Evaporation ⇒ The process of change of a liquid into vapours at any                                                    temperature below its boiling point is known as Evaporation. 

Sublimation ⇒ Sublimation is the process in which solid state change                                                directly to gaseous state without changing in liquid state.

Condensation ⇒ Condensation is the the reverse process of Evaporation in                                          which gaseous state change into liquid state.
