Answer:
ion exchange is the exchange of ions of the same charge between an insoluble solid and a solution in contact with it, used in water-softening and other purification and separation processes.

hope this helped !
Answer:
In cases where the water freezes, a release of energy occurs to the environment, therefore energy is lost, and it begins to "cool down".
The term cooling in chemical science today is not well seen since it is not considered that this exists, but would be replaced by the term "absence or loss of heat".
It is considered that a body cools when its temperature decreases, and if it continues to decrease as in the case of water, a point will reach the freezing point, which in this case that of water is 0 degrees Celsius, therefore when the cooling overcomes this thermal barrier the water solidifies "freezing"
Explanation:
In the case of pure water (H2O), the freezing point is 0 ° C. This means that, as long as it is at a temperature above 0ºC and below 100ºC (since that is its boiling point), the water will be in a liquid state.
