Tricky Question: Exothermic or Endothermic?

Is this process exothermic or endothermic? Actually, it depends on what we consider the system, and what we consider the surroundings. Every process can be exothermic or endothermic, depending on your point of view.

Phase Changes: Exothermic or Endothermic?

We will learn which phase changes and exothermic, and which are endothermic. It all has to do with the direction of heat movement, or heat transfer. If heat transfers from the surroundings into a system, it is an endothermic process. If it transfers from a system into the surroundings, it is an exothermic process.
