Term | Definition |
A state of matter that has a definite shape and definite volume. | solid |
A solid that is made up of crystals in which particles are arranged in a regular, repeating pattern, and which have a definite MP/FP. | crystalline solid |
A solid made up of particles that are not arranged in a regular pattern, and has no definite MP/FP. | amorphous solid |
A state of matter that has no definite shape, but does have a definite volume. | liquid |
Any substance that can flow such as a liquid or a gas. | fluid |
The resistance of a liquid to flowing. | viscosity |
A state of matter with no definite shape or volume. | gas |
The measure of the average energy (kinetic) of the particles of a substance. | temperature |
A force pushing on a surface divided by the area of that surface. | pressure |
The relationship between the volume and the pressure of a gas; when volume increases, pressure decreases. (BVP) | Boyle's Law |
The relationship between the temperature and the volume of a gas; when temperature increases, volume increases. (CTV) | Charles's Law |
A diagram that shows how two variables are related. | graph |
A term used to describe the relationship between two variables whose graph is a strait line passing through the origin of a graph.(As one goes up, the other goes up. As one goes down, the other goes down.) | directly proportional |
A term used to describe the relationship between two variables whose graph forms a curve that slopes downward. (As one goes down, the other goes up.) | vary inversely |
The total energy of a substance's particles due to their movement or vibration. | thermal energy |
A form of energy that comes from chemical bonds. | chemical energy |
The principle that states that the total amount of energy remains the same before and after physical and chemical changes. | law of conservation of energy |
The change of state from solid to liquid. | melting |
The change of state from liquid to solid. | freezing |
The change of state from liquid to gas. | vaporization |
The process that occurs when vaporization takes place only on the surface of a liquid. | evaporation |
The process that occurs when vaporization takes place inside a liquid as well as on the surface of the liquid. | boiling |
The change of state from a gas to a liquid. | condensation |
The change of state from a solid directly to a gas without passing through the liquid state. | sublimation |
A process in which substances undergo chemical changes, forming new substances with different properties. | chemical reaction |
