Everyone knows that the human body, which consists mostly of water, needs to receive fluids daily. Scientists have even derived a formula for water consumption per day, which comes from a person’s weight. The more it is, the more you need to drink.

But not all water is good for health. Plain tap water can hardly be called safe. It flows through pipes that are already quite a few years old, where there are many different deposits, rust and other harmful substances. Public utilities do not accidentally add chlorine to such water: it needs disinfection. And residents are additionally trying to boil it to kill dangerous microorganisms.

What happens when boiling?

When the temperature of the water in the kettle rises to 100 degrees Celsius, water and oxygen molecules leave with the steam. But impurities, heavy metals, etc. – do not disappear anywhere, because they simply cannot evaporate. It turns out that the volume of water after boiling decreases, and the concentration of impurities only increases.

Malignant microorganisms, pathogenic bacteria, of course, die. Knowing this, some believe that the more boil, the more purified water will become. This is a big misconception. All the bacteria died already at the first boiling, the second time they did not kill.
