It takes energy to break chemical bonds. Therefore, this process is endothermic.
Conversely, when bonds form, energy is released. Bond formation is exothermic.
We can apply this to our understanding of melting (and boiling) points. We can also use this to understand what is happening at a particle level in an endothermic or exothermic chemical reaction.
