| Question | Answer |
|---|---|
| solid | A state of matter that has a definite shape and a definite volume |
| crystalline solid | A solid that is made up of crystals in which are arranged in a regular, repeting pattern |
| amorphous solid | A solid made up of particles that are not arrengesd in a regular pattern |
| liquid | A state of matter that has no definite shape but has a definite voloume |
| fluid | Any substance that can flow |
| surface tension | The result of an inward pull amon the molecules of a liquid that brings the molecules on the surface closer together; causes the surface to act as if it has a thin skin |
| viscosity | A liques resistance to flowing |
| gas | A state of matter with no definite shape or voloume |
| pressure | The force pushing on a surface divided by the area of a surface |
| melting | The change in state from a solid to a liquid |
| melting point | The temperature at which a substance changes from a solid to a liquid; the same as the freezing point, or temperature at which a liquid changes to solid |
| freezing | The changes in a state from a liquid to a solid |
| vaporazion | The change of state from a liquid to a gas |
| evaporation | The process by which by which molecules at the surface of a liquid of a liquid absorb enough energy to change to a gas |
| boiling | Vaporation that occurs at and below the surface of a liquid |
| boiling point | The temperature at which a liquid boils |
| condesation | The change of state from a gas to a liquid |
| sublimation | The change in state from a solid directly to a gas without the liquid state |
| Charles law | A principle that describes the relationship between the temperature and volume of a gas at constant pressure |
| directly proportional | A term used to descirbe the relationship between two variable those graph is a straight line passing through the point |
| Boyle's law | A principle that describes the relatuonship between the pressure and volume of a gas at constant temperature |
| inversely proportion | A term of measurement based on multiples of ten and on established measures of mass, length, and time |
