Matter States
Solid liquid gas and changing states of matter (Galimberti)
| Question | Answer |
|---|---|
| Solid | A state of matter where the substance has a definite shape and volume |
| Solid | A state of matter where the substance's molecules are tightly packed and vibrate in place |
| Liquid | A state of matter where the substance has a definite volume and indefinite shape |
| Liquid | A state of matter where the substance's molecules are close together but move fast enough to be able to slide by each other |
| Gas | A state of matter where the substance has an indefinite shape and indefinite volume |
| Gas | A state of matter where the molecules move fast and freely |
| Melting | A change in state from a solid to a liquid |
| Freezing | A change in state from a liquid to a solid |
| Condensation | A change in state from a gas to a liquid |
| Vaporization | A change in state from a liquid to a gas |
| Sublimation | A change in state from a solid to a gas |
| Melting/Freezing point of water | 0 celsius (32 Fahrenheit ) |
| boiling point of water | 100 celsius (212 Fahrenheit) |
| endothermic change | A phase change involving a gaining of heat energy |
| exothermic change | A phase change involving a loss of heat energy. |
| endothermic change | melting, vaporization, sublimation |
| exothermic change | freezing, condensation, desublimation |
| deposition | A change in state from a gas to a solid |
| boiling | vaporization from within a liquid |
| evaporation | vaporization from the liquids surface |
| temperature increasing | speed of molecules increasing |
| temperature decreasing | speed of molecules decreasing |
| Kinetic energy increasing | speed of molecules increasing |
| Kinetic energy decreasing | speed of molecules decreasing |
