| Question | Answer |
| Matter | anything that takes up space and has mass. |
| Everything is made of | particles |
| These particles are | always moving |
| Each pure substance has it’s own type | of particle |
| When these particles gain energy, they | move faster and need more space |
| When these particles lose energy, they | move slower and need less space |
| expands | increases in volume “gets bigger” |
| contracts | decreases in volume “gets smaller” |
| The Four states of matter are | Solid, liquid, gas, plasma |
| Solidification (Freezing) | when a liquid turns into a solid |
| Fusion (melting) | when a solid turns into a liquid |
| Condensation | when a gas turns into a liquid |
| Evaporation | when a liquid turns into a gas |
| Sublimation | when a gas turns into a solid or a solid turns into a gas without turning into a liquid. |
| Temperature | The average kinetic energy |
| Thermometer | A device used to measure temperature. |
| Celsius | temperature scale used in Canada |
| Fahrenheit | Temperature scale used in the US |
| Freezing temperature of Water | 0 oC |
| Boiling temperature of Water | 100 oC |
| Body temperature | 37 oC |
| Room temperature | 20 oC |
| kinetic Energy | the energy of moving particles |
| Thermal energy | the TOTAL kinetic energy in an object |
| Heat | The transfer of thermal energy between two things that are at different temperatures |
| thermocouple | a thermometer that uses electricity to measure really high temperatures |
| bimetallic strip | a thermometer with two metals bonded together that expand and contract at different rates - it bends the metal strip |
| clinical thermometer | a thermometer used to measure human temperature |
| infrared thermogram | a video thermometer that shows different temperatures as colours |
| lab thermometer | the thermometer we use in science class |
