| three states of matter | solids, liquids, gases |
| What is matter made up of? | atoms and molecules |
| describe particles of matter | always moving & bumping into each other |
| solids | definite shape & volume |
| solid particles | close together & vibrating |
| crystalline solids | form a pattern; specific melting point |
| crystalline solid examples | iron, diamonds, ice, sand, salt |
| amorphous solids | no pattern; get softer when heated |
| amorphous solid examples | glass, rubber, wax, plastic, butter |
| liquids | definite volume, no definite shape |
| liquid shape | shape of its container or a puddle |
| liquid particles | close together, but move freely |
| surface tension | a force that acts on the particles at the surface of a liquid |
| viscosity | the resistance of a liquid to flowing |
| high viscosity | high resistance---flows slowly |
| low viscosity | low resistance---flows quickly |
| high viscosity examples | ketchup, honey, syrup |
| low viscosity examples | water, tea, coffee, pop |
| gases | no definite shape, no definite volume |
| gas shape & volume | match their container |
| gas particles | far apart; fly at high speeds |
