About that one can only boil water once, surely, all our readers. However, the reasons for this recommendation can be answered only by one. Today we will talk about what happens to the precious liquid during boiling, and what threatens to boil again.
Despite the fact that the composition of the water molecule is known to everyone - two hydrogen atoms and one oxygen atom, this colorless liquid contains a lot of impurities, most of which not only are not useful, but can even harm our body. What happens during boiling? All bacteria and microbes contained in water die( actually, for this we boil water), but at the same time, water molecules and oxygen evaporate at 100 degrees Celsius, while the impurities remain in the water, and their concentration increases dramatically. The contained hydrogen atoms do not die as the temperature rises, but settle to the bottom and thus weight the fluid. Chlorine, which is necessarily contained in water poured from the taps in our apartments, when heated, re
