Be amazed! Learn about the 12 most remarkable curiosities of water

 

How many days can you survive without water? Why should we not ingest sea water? What are the fruits or vegetables that contain the most water? Can water be in solid, liquid and gaseous states at the same time?

Water is part of our body, plants, animals and the environment. Without water we cannot live.

About 70% of the planet's surface is covered by water . Of this total, 67.5% is salty and only 2.5% is fresh water. Is all the fresh water available to us? No , because of all the fresh water on the planet, 69.7% is frozen at the poles and glaciers, 30% is found in aquifers and 0.3% is found on the surface of the highlands, for example, in rivers, lakes, wetlands, etc.

Water gives us life, and it surprises us!

That is a general look, but in particular there are a series of facts or curiosities that you may not know about water . Here we share them, you will be surprised!

1. The human body is made up of 60% water . This is an average, because at a younger age the percentage of water that our body contains is greater.
2. A human being in good physical condition can go up to a month without eating food, but at most, barely a week without drinking water .
3. When we feel thirsty it is because we have lost about 1% of the total water in our body.
4. One in three people in the world lives without clean water .
5. Cucumber and lettuce are some of the vegetables or fruits that contain the most water : 97%. They are followed by: Pumpkin (95%), celery (95%), radish (95%), tomato (95%), green pepper (93%), watermelon (92%), strawberry (92%), melon (90%) ), among others such as pineapple, apple, orange or lemon.
6. Seawater should not be consumed by humans, as it causes dehydration due to the large amount of salt it contains . For the same reason, it causes the body to eliminate more water than it needs in an effort to get rid of the salts.
7. Freshwater animals are going extinct 5 times faster than land animals. This figure is due to overexploitation, pollution and the decrease in flows.
8. Water is the only substance that you can find in liquid, solid and gaseous states .
9. Water in solid state (ice) increases its volume, but decreases its density ; that's why ice floats.
10. A poorly closed tap that leaks can waste about 75 liters of water per day .
11. Two hydrogen atoms and one oxygen atoms make up a water molecule (H ₂ O).
12. With a temperature of 0.01 ° Celsius and a pressure of 0.00603 atmospheres (or 611.73 pascals) the triple point of water is produced, that is, it coexists in the solid, liquid and gaseous states.
