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 Structure When 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 Structure The 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 Bonds Because 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
16. A single water molecule may be involved in as many as 4 hydrogen bonds at the same time.
18. Vocabulary Review What is makes a water molecule POLAR? http://img.metro.co.uk/i/pix/2008/03/polarbearswimR_450x350.jpg
19. A polar molecule has an unequal distribution of electrons; the two ends of the molecule have opposite charges. http://www.sogmin.org/Newsletters/2011%20NLs/positive-negative.jpg
