These are the riddles about water and relationships with it that we have collected for you. Of course, many of them are already somewhat outdated. And the situation with water now is simpler than thirty years ago. You can, for example, call one of the water supply companies, such as http://www.aqualader.ru/, and they will bring water directly to our home. But this is on the one hand. On the other hand, who would have thought relatively recently that plain water will you need to buy? However, this is a completely different song.
And we hope you liked these riddles about water, snow, rain, steam and other states of water. And you will be happy to look at others on our website. There is a lot of interesting things there: from to. And 44 more different collections. See for yourself!

The Neva is the main water artery of St. Petersburg. Current ecological state of water.
The Neva River originates in the Shlisselburg Bay of Lake Ladoga and flows into the Neva Bay of the Gulf of Finland. The length of the river is 74 km. Considering that the Neva originates in Lake Ladoga, it carries water that came from a vast area located on the territory of the Republic of Karelia, Leningrad, Novgorod, Pskov, Tver, Vologda, Arkhangelsk regions, Vitebsk region of the Republic of Belarus. In addition, 20% of the Neva basin is located within Finland.
For many years, studies of water quality in the Neva River have been carried out in St. Petersburg. Water samples are taken from 6 sections of the Neva and another 12 rivers of the Neva delta. Water is tested according to 48 parameters. Among them is the presence of a number of heavy metals, petroleum products, and mineral salts.

But at air temperatures below 0°C it turns into ice
or snow.
It has no taste, smell or color.
Water boils at t = 100°C. And turns into steam.
It may look like this.
ρ water = 1 g/cm3 (at 4°C)
ρ water = 1 g/cm3 (at 4°C)
Water does not conduct electricity;
Conducts heat poorly;
Has high heat capacity.
If water behaved “as expected,” then the Earth would simply become unrecognizable!
The Neva River originates in the Shlisselburg Bay of Lake Ladoga and flows into the Neva Bay of the Gulf of Finland. The length of the river is 74 km. Considering that the Neva originates in Lake Ladoga, it carries water that came from a vast area located on the territory of the Republic of Karelia, Leningrad, Novgorod, Pskov, Tver, Vologda, Arkhangelsk regions, Vitebsk region of the Republic of Belarus. In addition, 20% of the Neva basin is located within Finland.
For many years, studies of water quality in the Neva River have been carried out in St. Petersburg. Water samples are taken from 6 sections of the Neva and another 12 rivers of the Neva delta. Water is tested according to 48 parameters. Among them is the presence of a number of heavy metals, petroleum products, and mineral salts.
A person can live only three days without water, while without food 30 – 50 days.

All bodies expand when heated and contract when cooled. Everything except water. In the t range from 0°C to +4°C, water expands when cooled, and contracts when heated. At +4°C water has the highest density (1000 kg/m3). At lower and higher t°C, the density of water is slightly less.
Water, cooling from above, sinks down to the bottom only until its t°C reaches +4°C. Then, in a standing reservoir, the t°C distribution shown in the figure is established.
CONCLUSION:
Water is a unique substance in nature, the most important on the planet.
Chemical properties of water
A water molecule consists of two hydrogen molecules and one oxygen molecule.
Water is a dipole, i.e. particle having negative and
positive poles, because Oxygen is more electronegative than hydrogen, and it displaces electrons towards itself, creating a partial negative charge on it and a partial positive charge on hydrogen.
Hydrogen bond in
molecule
water
Hydrogen bonding is the ability of water to form hydrogen bridges between oxygen atoms of two hydrogen molecules located next to each other so that the hydrogen atoms are located on the segment connecting the oxygen atoms. In general, the structure of water appears as a mixture of all kinds of hydrant structures that can form in it.
