The document discusses several interesting facts about water molecules and their structure: - Water molecules are polar, with hydrogen atoms having a slight positive charge and oxygen having a slight negative charge. This allows water molecules to form hydrogen bonds with other water molecules. - A single water molecule can form up to four hydrogen bonds simultaneously. The ability of water to form these bonds gives it many unique properties. - Too much water consumption can cause a sodium imbalance in the blood known as hyponatremia. Most of the human body and planet are made up of water.

2. Interesting Facts About WaterThe most abundant compound in most living things is water.

3. 70% of an adult's body is water

4. Water dissolves more substances than any other liquidhttp://www.idswater.com/Common/header/Img-water.jpg

5. Facts ContinuedDrinking too much water can cause water intoxication. It occurs when water dilutes the sodium level in the bloodstream & causes an imbalance of water in the brain. This condition is termed at hyponatremia.http://3.bp.blogspot.com/_wrMEmICX6EI/THd2SJ0pZCI/AAAAAAAACwg/CMNOLDd1Kcg/s400/HYPONATREMIA+1.JPG

6. Facts ContinuedThe earth is a closed system, similar to a terrarium, meaning that it rarely loses or gains extra matter. The same water that existed on the earth millions of years ago is still present today.http://www.steripen.com/stuff/contentmgr/files/1/ed19577e905f1bed35a5910f3da70b33/misc/global_water01.jpg

7. Facts ContinuedMuch more fresh water is stored under the ground in aquifers than on the surface.http://www.fijiwater.com/wp-content/uploads/2010/06/Fiji_1_Water_072310_Aquifer.jpg

8. Facts ContinuedThe U.S. uses about 346,000 million gallons of fresh water every day.

9. By the time a person feels thirsty, his/her body has lost over 1% of its total water amount.

10. The weight a person loses directly after intense physical activity is weight from water... not fat!http://surveywater.files.wordpress.com/2009/12/earth-water-tap-supply-thumb4824558.jpg

11. Molecular StructureWhen hydrogen and oxygen combine to form water, water is the PRODUCT.http://quantumfreak.com/wp-content/uploads/2008/10/hydrogen-oxygen-and-water.jpg

12. Molecular StructureThe oxygen atom is on one end of the molecule & the hydrogen atoms are on the other end. The oxygen end of the molecule has a slight negative charge and the hydrogen end of the molecule has a slight positive charge.http://xnet.rrc.mb.ca/rcharney/The%20water%20molecule_files/molecul2.jpg

13. Why is the H2O Molecule Polar?A water molecule is polar because there is an uneven distribution of electrons between the oxygen & hydrogen atoms.http://www.school-for-champions.com/chemistry/images/polar_molecules-h2o.gif

14. Hydrogen BondsBecause of their partial (+) & (-) charges, polar molecules such as water can attract to each other. http://library.thinkquest.org/26153/habitat/images/molekule.gif

15. Hydrogen bonds are not as strong as covalent or ionic bonds, but water's ability to form multiple hydrogen bonds is responsible for many of its special properties.http://www.essenceoflife.com/images/science/figure1.gif
