|
matter |
Anything with mass and volume. |
|
|
mass |
The amount of material that makes up an object. |
|
|
volume |
The amount of space taken up by a substance or object. |
|
|
kinetic energy |
The energy of motion. |
|
|
kinetic molecular theory |
An explanation of the behaviour or molecules in matter. |
|
|
thermal expansion |
An increase of volume in a substance when its temperature is raised. |
|
|
thermal contraction |
A decrease in volume in a substance when its temperature is lowered. |
|
|
thermal energy |
The total energy of the particles making up a substance. |
|
|
heat |
Thermal energy transferred from a warmer material to a cooler material. |
|
|
temperature |
A measure of the average kinetic energy of the particles in a substance. |
|
|
melting |
The process of changing state from a solid to a liquid. |
|
|
evaporation |
The process of changing state from a liquid to a gas. |
|
|
condensation |
The process of changing state from a gas to a liquid. |
|
|
solidification |
The process of changing state from a liquid to a solid by the removal of heat. |
|
|
sublimation |
The process of changing state from a solid to a gas without going through the liquid stage. |
|
|
deposition |
In physics, the change in state of a substance from gas directly to solid without forming a liquid. |
|
|
melting point |
The temperature at which a solid begins to liquefy. |
|
|
boiling point |
The temperature at which a liquid changes into a gas. |
|
|
fluid |
A form of matter that can flow. Includes liquids AND gases. |
|
|
density |
The mass of a given volume. |
|
|
displacement |
The amount of space an object takes up when placed in a fluid. [How much the fluid moves UP when a solid is placed in a container of fluid.] |
