|---|
| capillarity | ability of water to climb the inside of narrow tubes |
| surface tension | strong force of attraction between water molecules that can support the weight of insects on lakes |
| cohesion | when water molecules are attracted to each other |
| mensicus | curved surface of water in a container |
| polar | a molecule that has + and - ends like a magnet |
| solute | a substance that is dissolved in a solution |
| universal solvent | water is called this because it dissolves so many different substances |
| pH | measurement of acidity or basicity |
| acid | low pH and high H+ ion concentration |
| base | high pH and high OH- concentration |
| neutral | pH of 7 |
| buffer | a weak acid OR base that prevents sudden changes in the pH of a solution |
| high specific heat | means that water can absorb a large quantity of heat before it changes temperature |
| ice is less dense than water | helps animals survive in the winter in lakes |
| water molecule | has an uneven distribution of electrons between oxygen and hydrogen |
| hydrogen "bond" | attraction of the hydrogen atom of one water molecule and the oxygen atom of another water molecule |
| high heat of vaporization | means that water releases a large quantity of heat when it evaporates |
| adhesion | when water molecules are attracted to other types of molecules by Hydrogen bonding |
| water ionization | when water molecules dissociate into H+ and OH- ions |
| molarity | moles of substance dissolved per liter |
