Why are freezing, condensation and deposition exothermic processes?

Answer 1

Since each of these necessitates the removal of heat from the system, they all slow down molecular motion.

Any process that causes the particles in the system to slow down as a result of heat flowing outward is exothermic, as the term "exothermic" refers to the release of heat from a system.

Accordingly, the three processes mentioned above are exothermic in relation to the system.

Freezing, condensation, and deposition are exothermic processes because they involve the release of heat energy as molecules transition from a higher-energy state (liquid or gas) to a lower-energy state (solid).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
