| adhesion | attraction of water molecules to moleculs of other substances |
| cohesion | attraction of water molecules to other molecules |
| capillary action | upward movement of water due to the attraction between water and other substances |
| surface tension | tightness that forms across water due to hydrogen bonding |
| hydrogen bonding | the attraction between hydrogen of one molecule to a negative atom of another molecule |
| polar molecule | molecule with electrically charged areas |
| universal solvent | water is called this because it dissolves so many other substances |
| alkalinity | measure of basicity |
| specific heat | amount of energy required to raise the temperature of 1 gram of a substance by 1 degree Celsius |
| hydrophilic | water-attracting |
| hydrophobic | water-repelling |
| acid | substance with high levels of hydrogen ions |
| base | a solution that has a high concentration of hydroxide ions |
| pH scale | tool used to measure acidity and basicity |
| neutral | neither acid nor a base; pure water |
