| Question | Answer |
|---|---|
| solid | a state of matter that has definite shape and a definite volume |
| crystalline solid | a solid that is made up of crystals in which particles are arranged in a regular repeating pattern |
| amorphous solid | a solid made up as particles that are not arranged in a regular pattern |
| liquid | a state of matter that has no definite shape but has a definite volume |
| fluid | a substance that can easily flow |
| surface tension | the result of a inward pull among the molecules on the surface closer together |
| viscosity | a liquid's resistance to flowing |
| gas | a state of matter with no definite shape or volume |
| melting | the change from solid to liquid state of matter |
| melting point | a temp. at which a substance changes from a solid to a liquid |
| freezing | the change from a liquid to a solid state of matter |
| vaporization | the change of state from a liquid to a gas |
| evaporation | the process that occurs when vaporization takes place only of the surface of a liquid |
| boiling | the process that occurs when vaporization takes places inside a liquid as well as on the surface |
| boiling point | the temp. at which the substance changes from a liquid to a gas |
| condensation | the change from the gaseous to the liquid state of matter |
| sublimation | the change in state from a solid directly to a gas without passing through the liquid state. |
