Properties of Water
| Question | Answer |
|---|---|
| Polar | Unequal sharing of electrons |
| Hydrogen bonding | is the force that holds water molecules to each other and other objects (weak attractions) |
| Cohesion | The tendency of water molecules to stick together because of hydrogen bonding. |
| Adhesion | Water molecules sticking to something other than water due to attraction of charges. |
| Capillary action | The tendency of water to move along the surface of a substance due to adhesion. Water molecules pull each other up. |
| Surface tension | A special form of cohesion that causes the surface of water to resist rupture. |
| Universal solvent | Water can dissolve many substances due to the partial changes within the water molecule. |
| Specific heat capacity | Specific heat is the amount of heat energy needed to raise temperature of water. Water has a high specific heat. |
| Hydrophillic | Substances that dissolve in water (water loving). Salt and sugar are hydrophillic because they can dissolve in water. |
| Hydrophobic | Substances that do not dissolve in water (water fearing). Oils are hydrophobic and do not mix with water. |
