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 |
Thermocouple | a thermometer that uses electricity to measure high temperatures. |
Bimetallic Strip | two different metals bonded together that expand and contract in different amounts - it bends |
Clinical thermometer | used to measure human body temperatures |
Infrared thermogram | different temperatures seen as colours. |
Laboratory Thermometer | A thermometer used for experiments |
Kinetic Energy | energy of moving particles |
Thermal Energy | the TOTAL kinetic energy |
Heat | the TRANSFER of thermal energy |
