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.
.Answer:
stay the same the conc. of a solution is the same throughout the liquid
Explanation:
If my understanding is correct, what this saying is referring to is the conversion of energy from relatively useful forms to heat energy (which is relatively useless).
As you probably know, conservation of matter says that matter can be neither created nor destroyed. You may also be aware of the conservation of energy, which states that energy can be neither created nor destroyed, but only converted from one form to another. Whenever you have a chemical process, a complicated process called entropy is what drives the process (you don't need to know exactly what this is, but if you want to, you can look up the second law of thermodynamics). Part of that process often involves energy being converted to different forms--from useful forms (that can do work) to useless forms (that can't do work). Useful forms of energy are "useful" because they can do work, and in the process are converted to heat, which is not very useful for work, and generally cannot be converted back to useful forms. Matter, on the other hand, does not have "useful" and "useless" forms.
