| A | B |
|---|
| solids | definite shape and definite volume |
| liquids | no definite shape, takes the shape of it's container, definite volume |
| gases | no definite shape, no definite volume |
| plasma | found in the universe and requires the most energy |
| crystalline | Solids have this shape |
| amorphous | when a solid can shange its shape |
| repeating | solids have this type of pattern |
| vibrate | solids are only able to do this because of how close the particles are to one another |
| move freely | the aprticles in a liquid ___________ ____________ over and under eachother |
| bounce off | The particles in a gas __________ _____________ one another |
| least amount | Solids require the ____________ _____________ of energy |
| most amount | Plasma requires the ____________ _____________ of energy |
| viscosity | a liquid's resistance to flow |
| honey, catsup | Liquids with a high viscosity |
| thicker | the ___________ the liquid, the higher the viscosity |
| Boyle's Law | describes the relationship betweeen pressure and volume |
| Charle's Law | between temperature and volume |
| Boyle's Law | As volume increases the pressure decreases |
| Charles' Law | as the temp increases or decreases so does the volume |
| Gases | Phase of matter which expands or contracts |
| condensation | changing from a gas to a liquid |
| vaporization | changing from a liquid to a gas |
| freezing | changing from a liquid to a solid |
| melting | changing from a solid to a liquid |
| sublimation | changing from a solid to a gas skipping the liquid state |
| increase | liquid changing to a gas causes an ____________ in heat energy |
| decrease | liquid changing to a solid requires a _____________ in heat energy |
| freezing point | the temp. where a liquid turns into a solid a 0 degrees celcius |
| melting point | the temp where a solid turns into a liquid at 0 degrees celcius |
| boiling point | the temp where a liquid turns into a gas at 100 degrees celcius |
| temperature | remains constant during a phase change |
| physical changes | color, shape, texture, and size are examples of this type of change |
| chemical changes | a new substance is created |
| physical changes | only changes phase does not create a new substance |
| reversed | Only physical changes can be _____________ meaning that it can get back to its original state |
| flammability | a substances ability to burn |
| chemical reaction | a chemical change is also known as a |
