Matter States
Solid liquid gas and changing states of matter (Galimberti)
| Question | Answer |
|---|---|
| cohesion | The attractive force between like molecules |
| adhesion | The attractive force between unlike molecules |
| surface tension | The cohesive force of a liquid at the surface |
| capillary action | The rise and fall of a liquid in a narrow tube or space |
| Boyle's Law | Under a constant temperature, when the pressure of a gas goes up, the volume goes down |
| Charles's Law | Under a constant pressure, when the temperature of a gas goes up, the volume goes up |
| 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 | Particles gain energy. The particles begin to move fast enough to overcome some attractions and begin to move. |
| Vaporization | Particles gain energy. The particles begin to move fast enough to overcome the attractions and begin to move freely. |
| Condensation | Particles lose energy. The particles begin to slow down enough and attract more to each other and begin to clump together. |
| Freezing | Particles lose energy. The particles begin to slow down so much that the attraction overcomes motion and particles lock in place. |
| Sublimation | Particles gain energy. The particles begin to move fast enough to completely overcome the attractive force that locks the particles in place and allows them to break free. |
| Melting/Freezing point of water | 0 celsius (32 Fahrenheit ) |
| Vaporization/Condensation 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 |
| desublimation | A change in state from a gas to a solid |
| boiling | vaporization from within a liquid |
| evaporation | vaporization from the liquids surface |
| polar molecule | a molecule that is has electrically charged areas |
| uniqueness of water | exists in all 3 phases naturally on earth; gets less dense when it freezes |
| crystalline solid | A solid that has molecules that are arranged in an orderly repeating pattern |
| amorphous solid | A solid that has molecules that are not arranged in an orderly repeating pattern |
| crystalline solid | ice |
| amorphous solid | glass |
| Boyle's law | ex. push down on a bicycle pump and the pressure increases |
| Charles' Law | ex. leave a balloon in the cold and it deflates |
