15 interesting and surprising facts about water

Water is the simplest and most familiar substance on the planet. But at the same time, the water is fraught with many mysteries. Scientists are still investigating it, finding more and more interesting data about water.

Fact one:the cleanest water in Finland
According to UNESCO, the cleanest water is in Finland. A total of 122 countries participated in the study of fresh natural water. At the same time, 1 billion people around the world do not have access to safe water at all.

Fact two:get ice faster from hot water
Which water turns to ice faster: hot or cold? If you think logically, then, of course, cold. After all, you need to cool down hot first and then freeze, but you do not need to cool down cold. However, experiments show that it is hot water that turns into ice faster. An exact answer to the question of why hot water freezes faster than cold still does not exist. Perhaps it is the difference in supercooling, evaporation, ice formation, convection, or the reason for the effect of liquefied gases on hot and cold water.

Fact three:water overcooling
Everyone remembers well from the school course of physics that water freezes at 0 degrees, and at 100 degrees boils. However, there is a so-called over-cooling of water. This property has a very clean water - no impurities. Even when cooled below freezing, such water remains liquid. But in both cases there are temperatures at which water becomes ice or boils.

Fact Four:water has more than 3 states
From school everyone knows that water has 3 state of aggregation: liquid, solid and gaseous. However, scientists identify 5 different states of water in liquid form and 14 states in frozen form.

Fact Five:water is like glass
What happens if you take frozen clean water and continue cooling? With water, miraculous transformations will occur. At minus 120 degrees Celsius, water becomes ultra-viscous or viscous, and at temperatures below minus 135 degrees it turns into "glass" water. "Glass" water is a solid, in which there is no crystal structure, as in glass.

The sixth fact:the basis of life is water
Water is the basis of life. All living animals and plant creatures consist of water: animals - by 75%, fish - by 75%, jellyfish - by 99%, potatoes - by 76%, apples - by 85%, tomatoes - by 90%, cucumbers - by 95 %, watermelons - 96%. Even man is made of water.86% of the water is contained in the body of the newborn and up to 50% in the elderly.

Fact Seven:water is a disease carrier
Water not only gives life, but can take it away. 85% of all diseases in the world are transmitted by water. Every year 25 million people die from these diseases.

Fact eight:a man dies without water
If a person loses 2% of water from the mass of his body, then he will have a strong thirst. If the percentage of water lost increases to 10, then the person will start hallucinations. With a loss of 12%, people will not be able to recover without the help of a doctor. With a loss of 20%, a person dies.

Fact nine:most fresh water in glaciers
Where is the most water? The answer seems obvious: in the oceans. However, in reality, the Earth’s mantle contains 10–12 times more water than in the World Ocean. At the same time, almost all the mass of water on the planet is not suitable for drinking. We can drink only 3% of water - that is how much fresh water we have. But even most of these 3% is unavailable, as it is contained in glaciers.

Fact ten:water as a diet
With the help of water you can fight with excess weight. By drinking only water from drinks, you can dramatically reduce the total caloric intake.Firstly, because a person stops drinking high-calorie sweet drinks and juices, secondly, because after water he pulls less to take sweets, as is the case with tea or coffee.

Fact eleventh:water for a healthy heart
Water helps reduce the likelihood of a heart attack. During research, scientists found that those people who drink about six glasses of water a day are less at risk of a heart beat, unlike those who drink only two glasses.

Fact twelfth:35 tons of water for life
Without water, a person can live very long. The need for water is in second place after oxygen. Without food, a person can live for about six weeks, and without water for five to seven days. Throughout his life, a person drinks about 35 tons of water.

Fact thirteenth:the most expensive water
Water can be free, and can be very expensive. The most expensive water in the world is sold in Los Angeles. Manufacturers pack precious liquid with a balanced taste and ph value in bottles with Swarovski crystals. Such water is worth $ 90 for 1 l.

Fact fourteenth:there is water that burns
There is also dangerous water.For example, in Azerbaijan there is water in which there is a lot of methane, so it can catch fire if you bring a match to it. And in Sicily in one of the lakes there are underwater sources of acid that poison all the water in this reservoir.

Fact fifteenth: protein in water
Sea water is a very nourishing substance. In 1 cu. cm of this water contains 1.5 g of protein and other substances. Scientists believe that only the Atlantic Ocean in its nutritional value is estimated at 20 thousand harvests, which are harvested for the year throughout the land.
