Interesting facts about Water

282 points

Water is the most common substance on our planet. Somewhere between 70 and 75 percent of the Earth is covered in water, which is why it is called the Blue Planet. Without water, life is impossible not only for humans, but also for other living beings. Without food, a person can live up to a couple of weeks, and without water only a few days. It would seem that we know everything about water, but in fact, scientists continue to study the properties of water and still make amazing discoveries. March 22 is celebrated World Water Day. Water is the simplest and most familiar substance on the planet. But at the same time, water is fraught with many mysteries. Scientists still continue to study it, finding more and more interesting data on water.

March 22 is celebrated World Water Day. This holiday was established by decision of the United Nations General Assembly to remind humanity of the importance of water for the environment and the development of society.

Currently, 70% of our planet is covered by water. In this case, you can drink only 1% of this water. Every year, the problems of access to water resources become more acute. Over the past 50 years in the world there have been as many as 507 conflicts related to access to water. 21 disputes led to hostilities.

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

Finland's cleanest water

According to UNESCO, the cleanest water is in Finland. In total, 122 countries took part in the study of fresh natural water. At the same time, 1 billion people worldwide do not have access to safe water at all.

Ice is faster to get from hot water

Which water will turn into ice faster: hot or cold? Logically, of course, it's cold. After all, you need to cool down first hot, 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, after all, hot water freezes faster than cold water still does not exist. Perhaps the cause is the difference in hypothermia, evaporation, ice formation, convection, or the reason is the effect of liquefied gases on hot and cold water.

Water Supercooling

Everyone remembers well from the school physics course that water freezes at 0 degrees and boils at 100 degrees. However, there is the so-called supercooling of water. This property has very clean water - without impurities. Even when cooled below freezing, such water remains liquid. But in that, and in another case, there are temperatures at which water will become ice or boil.

water has more than 3 states

From school everyone knows that water has 3 states of aggregation: liquid, solid and gaseous. However, scientists distinguish 5 different states of water in liquid form and 14 states in frozen form.

water is like glass

What will happen if you take frozen clean water and continue cooling? Wonderful transformations will take place with water. At minus 120 degrees Celsius, the water becomes highly viscous or viscous, and at temperatures below minus 135 degrees it turns into “glass” water. "Glass" water is a solid substance in which there is no crystalline structure, as in glass.

The basis of life is water

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

water is the carrier of disease

Water not only gives life, but can also take it. 85% of all diseases in the world are transmitted through water. Every year, 25 million people die from these diseases.

a man dies without water

If a person loses 2% of the water of his body mass, then he has a strong thirst. If the percentage of lost water increases to 10, then the person will begin hallucinations. With a loss of 12%, a person will not be able to recover without the help of a doctor. With a loss of 20%, a person dies.

most of the fresh water - in the glaciers

Where is the most water? The answer seems obvious: in the oceans. However, in fact, the Earth’s mantle contains 10-12 times more water than in the World Ocean. Moreover, almost all the mass of water available on the planet is not suitable for drinking. We can only drink 3% of the water - that’s how much fresh water we have. But even most of these 3% are not available, as they are found in glaciers.

water as a diet

Using water, you can fight excess weight. Drinking only water from drinks can dramatically reduce the overall calorie intake. Firstly, because a person stops drinking high-calorie sweet sodas and juices, and secondly, because after water he is less inclined to take sweets, as is the case with tea or coffee.

Water for a Healthy Heart

Water helps reduce the likelihood of a heart attack. During the studies, scientists found that people who drink about six glasses of water a day are less likely to have a heart beat, unlike those who drink only two glasses.

35 tons of water per life

Without water, a person can live very long. Water demand is in second place after oxygen. A person can live without food for about six weeks, and without water - five to seven days. Throughout his life, a person drinks about 35 tons of water.

the most expensive water

Water can be free, or it can be very expensive. The world's most expensive water is sold in Los Angeles. Manufacturers pack precious liquid with a balanced taste and ph value in bottles with Swarovski crystals. Such water costs $ 90 for 1 liter.

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 pond.

Protein in Water

Sea water is a very nutritious substance. In 1 cube cm of 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 over the whole land over the year.
