Water - the most simple and familiar substance on the planet. But at the same time, water conceals many mysteries. It still continues to investigate the scientists finding more interesting data on the water.

Fact one: the purest water in Finland
According to UNESCO, the pure water is in Finland. A total of fresh natural water 122 countries participated. While 1 billion people worldwide have no access to safe water. Fact two: ice faster to get out of hot water
What water quickly turned to ice: hot or cold? Logically, then, of course, cold. After all, one must first hot to cool, and then freeze, but the cold does not need to cool down. However, experiments show that the ice is faster turns hot water.
exact answer to the question, why did the hot water freezes faster than cold water, still does not exist. Maybe it's the difference in colds, evaporation, ice formation, convection, or cause exposure to liquefied gas for hot and cold water. Fact Three: supercooling water all remember from school physics course that water freezes at 0 degrees and boils at 100 degrees. However, there are so-called supercooling water. This property has very clean water - without impurities. Even when cooled below the freezing point of this water remains liquid. But in fact, and in another case there is a temperature at which water would boil or ice. Fact four: the water more than 3 states From school all know that water has 3 states of aggregation: 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: water like glass What happens if you take the frozen fresh water and continue cooling? With water miraculous transformations occur. At minus 120 degrees Celsius water becomes highly viscous or viscous, and at temperatures below minus 135 degrees it becomes a "glass" water. "Glass" water - is solid, wherein there is no crystal structure in the glass. Fact Six: the basis of life - water Water - the basis of life. All living animal and vegetable beings are composed of water: animals - 75%, fish - 75%, jellyfish - 99%, potatoes - by 76%, apples - 85%, tomatoes - 90%, cucumbers - 95 %, watermelons - by 96%. Even the man 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 - carrier of diseases Water not only gives life, but can also take it away. 85% of all diseases in the world is transmitted through water. Every year 25 million people die from these diseases. Fact Eight: people die without water If a person loses 2% water by weight of his body, he has a strong thirst. If interest is lost water will increase to 10, then the person will start hallucinating. With the loss of 12% of people will not be able to recover without the help of a doctor. With the loss of 20% of people die. Fact Nine: most fresh water - in glaciers where 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 on the planet mass of water is not potable. We can drink only 3% water - so much we freshwater. But even most of the 3% is not available, since it is contained in glaciers. Fact Ten: water as a diet with water can fight obesity. Eating of drinks only water, you can dramatically reduce the overall caloric intake. First, because a person stops drinking calorie sugary sodas and juices, and secondly, because after less water pulls take sweets, as in the case of tea or coffee. Fact Eleven: Water for a Healthy Heart Water helps reduce the risk of heart attack. During the study, researchers found that people who drink about six glasses of water per day, less risk of heart attack, in contrast to those who drank only two glasses. Fact Twelve: 35 tons of water for life without water a person can live a very short time. The demand for water is in second place after oxygen. Without food a person can live for about six weeks, and without water - five to seven days. In all his life a person drinks about 35 tons of water. Thirteenth fact: most expensive water Water can be free, and can be very expensive. The most expensive in the world of water is sold in Los Angeles. Manufacturers packed the precious liquid with a balanced taste and value ph in bottles with rhinestones "Swarovski". Cost is a $ 90 water per 1 liter. Fourteenth fact: there is water that burns there and 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 the lakes there are underwater acid sources that poison all the water in the pond. Fifteenth fact: protein in water Seawater - very nutritious substance. In 1 cc. cm such water contains 1.5 grams of protein and other substances. Scientists believe that only one Atlantic Ocean on its nutritional value is estimated at 20 thousand harvests, which are collected for the year across the land.
