What Phase Changes Are Exothermic & Endothermic? | Sciencing
Here is how you would classify the phase changes as endothermic or exothermic: melting, evaporation and sublimation are endothermic processes while freezing, condensation and deposition are exothermic processes. When moving from a more ordered state to a less ordered state, energy input is required.

Endothermic vs. exothermic reactions (article) | Khan Academy
The teacher’s final comment to Sam and Julie about this experiment is, When trying to classify a reaction as exothermic or endothermic, watch how the temperature of the surrounding—in this case, the flask—changes. An exothermic process releases heat, causing the temperature of the immediate surroundings to rise.

At constant pressure, q is equal to the change in enthalpy (ΔH) for a process. If ΔH is positive, the process absorbs heat from the surroundings and is said to be endothermic. If ΔH is negative, the process releases heat to the surroundings and is said to be exothermic. Phase changes, chemical reactions, and the formation of solutions are …

Phase Changes of Matter (Phase Transitions) – Science Notes and Projects
A phase change or phase transition is a change between solid, liquid, gaseous, and sometimes plasma states of matter. The states of matter differ in the organization of particles and their energy. The main factors that cause phase changes are changes in temperature and pressure. At the phase transition, such as the boiling point between liquid …

What is an exothermic reaction? | Scientific American
Like phase changes, chemical reactions can occur with the application or release of heat. Those that require heat to occur are described as endothermic, and those that release heat as exothermic.
