10 interesting facts about water

We don't think too much about water,
that basic element without which 
there is no life.

We know that we need to drink it 
because our body needs it to 
function normally, 
we know that we pollute it 
excessively and we know that 
because of that same pollution we 
need to purify it before 
consuming it.
 

However, I'm sure you certainly 
didn't know the following facts 
about water.

1. There are 1.5 billion cubic 
kilometers of water on the 
planet Earth. That's 800 trillion 
Olympic pools.

2.If the water were evenly distributed throughout the planet Earth, the depth of that water surface would be 3,700 meters.

3. More water is found in the 
Earth's atmosphere than in all 
the rivers of our planet.

4.All the water on Earth arrived in comets and asteroids.

5.Water has a unique property, 
it expands when it freezes, 
unlike any other liquid. 
This property of water made it 
possible to create life. 
Under the ice crust of rivers 
and lakes during the ice age, 
life continued to develop.

6.The amount of water in the human body changes throughout life. The body of the fetus consists of 95 percent water, the body of the newborn 77 percent water, and the body of the adult consists of 60 to 70 percent water. The human brain is made up of 70 percent water, and every cell in the human body is made up of two-thirds water

7. A man can survive a month 
without food, but only a week 
without water.

8.Hot water freezes faster than cold water. This effect is called the Mpemba effect, and to date chemists have not offered an exact explanation for why this is so. In 2012, the British Royal Society of Chemistry held a competition in search of works that would offer a possible explanation for the Mpemba effect. Among more than 22,000 applications, the work of Nikola Bregović, an assistant at the Faculty of Science in Zagreb, won first place. His work was declared victorious by Erasto Mpemba himself.

9. One water flush in the toilet 
requires approximately 8 liters 
of water, and the same amount of 
water is consumed when 
brushing teeth.

10. If water drips from a broken 
tap every second, as much as 760 
liters of water leak out 
every year!

I'm sure you didn't know most of these facts about water. Will you keep it better now? How much do we actually think about such small and so important things for us ?!
