15 interesting facts about water
Water - the most simple and familiar substance on the planet. But at the same time, the water carries a lot of mysteries. She still continue to investigate the scientists are finding more interesting data about water. Fact one: the purest water in Finland
According to UNESCO, the purest water is in Finland. A total of fresh natural water 122 countries participated. This 1 billion people worldwide do not have access to safe water.
Fact two: the ice quickly get out of hot water
Which water quickly turned to ice: hot or cold? Logically, then, of course, cold. It must first be hot to cool, and then freeze, but the cold does not need to cool down. However, experience shows that the ice is fast becoming the hot water.
The exact answer to the question, why did the hot water freezes faster than cold, still does not exist. Maybe it's the difference in the supercooling, evaporation, ice formation, convection, or the reason for the impact of diluted gases at the hot and cold water.
Fact Three: supercooled water
All remember from school physics course, that water freezes at 0 degrees and boils at 100 degrees. However, there are so-called supercooled water. This property has a very clean water - without additives. Even when cooled below the freezing point of this water remains liquid. But in fact, in both cases there is a temperature at which water would boil or ice.
Fact four: the water for more than 3 states
From school everyone knows that water has a 3: liquid, solid and gaseous. However, scholars have identified 5 different states of water in liquid form, and 14 states in the frozen form.
Fact five: the water like glass
What happens if you take the frozen pure water and continue cooling? With water there will be miraculous transformations. At minus 120 degrees Celsius water is extra-viscous or viscous, and at a temperature below minus 135 degrees it becomes a "glass" water. "Glass" water - a solid, which lacks crystalline structure, both in the glass.
Fact Six: the foundation of life - water
Water - the basis of life. Every living animal and vegetable substance composed of water: animals - 75%, fish - by 75%, jellyfish - by 99%, potatoes - by 76%, apples - 85%, tomatoes - 90%, cucumbers - 95 %, watermelons - 96%. Even a person is out of the water. 86% of the water contained in the body of a newborn and up to 50% in the elderly.
Fact Seven: Water - disease vectors
Water not only gives life, but it can also take it away. 85% of all diseases in the world transmitted through water. Every year, 25 million. People die from these diseases.
Fact Eight: man dies without water
If a person loses 2% water by weight of his body, then he has a strong thirst. If the percentage of lost water increase to 10, then the person will start hallucinating. If you lose 12% of people will not be able to recover without the help of a doctor. If you lose 20% the person dies.
Fact Nine: the biggest fresh water - glaciers
Where are the most water? The answer seems obvious: in the oceans. But in fact, in the mantle of water contains 10-12 times more than in the oceans. Moreover, almost all available in the world body of water not suitable for drinking. We can drink only 3% of the water - that is how much we freshwater. Even most of the 3% is not available, as is contained in glaciers.
Fact Ten: water as diet
With water you can fight obesity. Eating out drink only water, you can dramatically reduce the total caloric intake. Firstly, because the person stops drinking high-calorie sweet drinks and juices, and secondly, because after less water pulls take sweets, as is the case with tea or coffee.
Fact Eleven: Water for a Healthy Heart
Water helps reduce the chance of a heart attack. During the study, researchers found that those who drink about six glasses of water a day, lower risk of heart attack as opposed to those who drink only two cups.
The fact of the twelfth 35 tons of water for life
Without water a person can live a very short time. Water demand is the second place after the oxygen. Without food a person can live about six weeks, but without water - five to seven days. Throughout his life a person drinks about 35 tons of water.
The fact of the thirteenth: the most expensive water
Water may be free, and can be very expensive. The most expensive water in the world is sold in Los Angeles. Manufacturers pack a precious liquid with a balanced taste and value ph in bottles with pastes «Swarovski». Should such water 90 $ for 1 liter.
The fact of the fourteenth: there is water that burns
There is a dangerous water. For example, in Azerbaijan there is water in which a lot of methane, so it can catch fire if exposed to a match. And in Sicily in one of lakes there are underwater sources of acid which poison all the water in the pond.
The fact of the fifteenth: the protein in water
Sea water - rather nutritious substance. In 1 cu. refer to such water contains 1.5 g of protein and other substances. Scientists believe that the Atlantic Ocean alone in its nutritional value is estimated at 20 thousand. Crops, which are collected for the year across the land.
