|
Solid |
A state of matter that has a definite volume and a definite shape |
|
|
Fluid |
Any substance that can flow |
|
|
Gas |
A state of matter with no definite shape or volume |
|
|
Liquid |
A state of matter that has no definite shape but has a definite volume |
|
|
Crystalline solid |
A substance that is made up of crystals in which particles are arranged in a regular, repeating pattern. Has a definite melting point |
|
|
Temperature |
A measure of the average energy of motion of the particles of a substance |
|
|
Pressure |
The force pushing on a surface divided by the area of that surface |
|
|
Boyle’s Law |
The relationship between the PRESSURE and VOLUME of a gas. When volume increases, pressure decreases. |
|
|
Charle’s Law |
The relationship between the TEMPERATURE and VOLUME of a gas. When temperature increases, volume increases. |
|
|
Graph |
A diagram that shows how two variables are related |
|
|
Directly proportional |
A term used to describe the relationship between two variables whose graph is a straight line passing through the point (0,0) |
|
|
Vary inversely |
A term used to describe the relationship between two variables whose graph forms a curve that slopes downward |
|
|
Thermal energy |
The total energy of a substance’s particles due to their movement or vibration |
|
|
Viscosity |
The resistance of a liquid to flowing |
|
|
Law of conservation of energy |
The principle that states that the total amount of energy of a substance remains the same during physical or chemical change |
|
|
Melting |
The changing of state from solid to liquid |
|
|
Freezing |
The changing of state from liquid to solid |
|
|
Vaporization |
The change of state from a liquid to a gas |
|
|
Evaporation |
The process that occurs when vaporization takes place only in the surface of a liquid |
|
|
Boiling |
The process that occurs when vaporization takes place inside a liquid, as well as on the surface |
|
|
Condensation |
The change of state from gas to liquid |
|
|
Sublimation |
The change in state from a solid directly to a gas without passing through the liquid state |
|
|
Chemical energy |
A form of energy that comes from chemical bonds |
|
|
Amorphous solid |
A solid made up of particles that are not arranged in a particular pattern- no set melting point, solid gets softer |
|
|
Chemical reaction |
A process in which substances undergo chemical changes, forming new substances with different properties |
