| Question | Answer |
|---|---|
| Definite volume and definite shape | solid |
| . Definite volume but no definite shape | liquid |
| No definite shape nor volume | gas |
| resistance of a liquid to flow | viscosity |
| plastics, rubber and glass (particles not arranged in a regular pattern) | amorphous solid |
| regular repeating pattern (salt, sugar, sand, and snow) | crystalline solid |
| when a solid melts | melting point |
| measure of the average energy of particles | temperature |
| force of its outward push divided by the area of the walls of the container | pressure |
| pressure increase, volume decreases | Boyle's Law |
| when temperature decreases, volume decreases | Charles' Law |
| Flows from warmer substance to a cooler substance | Thermal energy |
| Lose energy to become a liquid | condensation |
| Specific temperature at which a liquid boils | boiling point |
| Liquid gains enough energy to become a gas | evaporation |
| Surface particles of a solid gain enough energy to become a gas | sublimation |
| Takes place only on the surface of a liquid | evaporation |
| A diagram that shows how two variables are related. | graph |
| A term used to describe the relationship between two variables whose graph is a straight line passing through the point.Also the relationship in Charles Law (Temp - up , volume - up) | directly proportional |
| Shows the relationship on a graph with the line curving steeply close to the vertical axis and less steep close to the horizontal axis in a graph. Also shown in Boyle's Law as (volume - decrease, pressure - increase) | inversely proportional |
| Change in state from a solid to a liquid. | melting |
| Change in state from a liquid to a solid. | freezing |
| Second kind of vaporization that takes place inside the liquid as well as at the surface. | boiling |
