Across
- 2. The process where water sticks to other materials because of its polar nature.
- 5. Because of water's ______ specific heat, it can exist in 3 states (solid, liquid, and gas).
- 7. The upward force that fluid exerts on an object less dense than itself.
- 9. As salinity ______, water resists freezing (this is why salt is put on a road during ice/snow storms).
- 11. The process where, since hydrogen bonds are attracted to each other, water molecules stick together.
- 14. An action of water that explains why water is able to travel up a plant's xylem (against forces of gravity).
- 15. ______ includes the total quantity of all dissolved inorganic solids in seawater (ions).
- 16. Hydrogen bonds can easily break and ______.
- 18. Water's hydrogen atoms bond to the oxygen atoms with a ______ bond. Because of this bond, water is a very stable molecule.
Down
- 1. The positively charged hydrogen end of one molecule attracts the ______ charged oxygen end of another water molecule.
- 3. Water is a ______ solvent.
- 4. ______ tension is a skin-like surface formed due to the polar nature of water; water's resistance to objects attempting to penetrate its surface.
- 6. The type of pressure at a given depth that is the result of the weight of the liquid acting on an area at that depth plus air pressure.
- 8. The tendency for a fluid (liquid or gas) to resist flow (the colder water gets the more resistant to flow it becomes).
- 10. As water cools enough to change from a liquid to ice, the hydrogen bonds spread the molecules into a crystal structure that takes up more space than liquid water, so it ______.
- 12. Water forms ______ bonds.
- 13. Water is a ______ molecule.
- 17. Individual hydrogen ______ are weak compared to covalent ______.
