Water Properties
8.E.1.1
| Question | Answer |
|---|---|
| Adhesion | The property of water that allows it to be attracted to or stick to other substances |
| Adhesion-Cohesion | The two properties of water that work together and are responsible for a tree's ability to transport water from the roots all the way to top of the tree |
| Capillary action | the combined force of cohesion and adhesion that move against the force of gravity |
| Cohesion | the property of water responsible for water's ability to stick to other water molecules |
| Expansion | Occurs to water molecules when freezing; molecules arrange in a lattice-structure |
| It is less dense than liquid water | Frozen water (ice) floats because.. |
| H2O | the chemical formula for water (2 hydrogen and 1 oxygen) |
| Specific heat | The property of water that explains why coastal areas climates do not fluctuate as severely as further inland |
| High specific heat | Waters ability to absorb heat without drastically changing its temperature |
| Hydrogen | positive end of water |
| Oxygen | negative end of oxygen |
| Hydrogen bond | type of bond between two water molecules |
| Surface tension | this property allows a water strider to walk on the top layer of water without falling in |
| Polar | a molecule that has an uneven sharing of electrons (ones side more positive, the other side more negative) |
| Surface tension | the tightness on the top layer of water due to cohesion of water molecules |
| Universal Solvent | used to describe water because it dissolves many substances |
| Solute | The substance that is being DISSOlVED |
| Solution | a mixture that is formed with a solute dissolves in a solvent |
| Density | how tightly packed the atoms are in a substance water's density = 1 g/mL |
| Hydrophilic | "water-loving"; having a tendency to mix with, dissolve in, or be wetted by water. |
| Hydrophobic | "water-fearing"; tending to repel or fail to mix with water |
| Solvent | The substance that is doing the DISSOLVING substances |
