| Motions of particles differ in gasses, liquids, and solids |
|
Definition
| Gas particles=spread far apart and move in all directions at high speeds, filling all space available to them. Liquid particles=packed closely together but can move freely around each other and liquids take on the shapes of their containers. Solid particles are packed tightly together, they can vibrate, but not move from their fixed positions. |
