All the process that have arrow pointing up requires energy. So, they all will be endothermic
All the process that have arrow pointing down releases energy. So, they all will be exothermic
So, endothermic processes are:
Vapourization
Sublimation
Melting

A change of state, also known as a change of phase, is when a substance changes from one state of matter to another, such as changing from a liquid to a gas. A phase change is always associated with a change of heat, where the heat is either going into the substance or leaving the substance. Types of phase changes are melting, freezing, vaporization, condensation, and sublimation.
