| material | a specific kind of matter |
| mixture | contains 2 or more different materials |
| phase | a region with a uniform set of properties |
| interfaces | boundaries between different phases |
| solution | homogenus matter that can be classified as a mixture |
| solute | material which is dissolved |
| solvent | material into which solute is dissolved |
| substances | homogenous materials that always have the same solution i.e. elements and compounds |
| organic | contains carbon |
| inorganic | everything which does not contain carbon |
| physcial change | same substance remains after change |
| chemical change | a new substance is created |
| molarity | the amount of solute in a substance |
| precipitate | the dropping out of a substance as the solvent is reduced |
| crystallization | the formation of crystals as the solvent evaporates |
| physical property | length, color or temp |
| chemical property | describes the behavior of a substance in a chemical change |
| extensive property | depend on the amount of matter present |
| intensive | identify substance |
| endothermic | energy is absorbed, substance loses heat |
| exothermic | energy is given off, substance grow warmer |
| activation energy | the minimum energy needed to start a reaction |
| calorimeter | device used to measure the energy given off during a change |
| specific heat | the heat needed to raise the temp of 1 gram by 1ยบ C |
