1a) States of matter (kinetic particle theory (all matter consists of tiny…

- - - - random, irregular but still close to each other and touching occasionally
    - - moderate energy
    - - move around/past each other in a flowing motion
        -when heated they move more (expand)
    - - still present but has less effect than when solid
  - - - very fast and randomly but moving in straight lines. when particles collide/bounce off container walls, it is called pressure
    - - lots of energy
    - - random, very far apart. when heated move even further apart
    - - very weak/nonexistent forces
  - - - fixed uniform structure with particles close together (touching)
    - - small amount of energy
    - - vibrating but they do not move. when heated they vibrate more but still do not move
    - - strong forces (cannot go through)
- - - - heating
