Particles in montion

Matter is made of atoms and this atoms are in a costant motion. This is the basis for the "Kinetic theory of matter". Matter can be divided in: solid, liquid and gases.

SOLID: 
  -Has definate volume and shape
  -Particles are close and don´t move
  -Particles together form a regular pattern
  ~The particles vibrate, but they can not move from one part of the
    solid to another part
  ~Solid can not easily change in shpe or volume
         When it change is by breaking it




LIQUID: 
  -Define volume, but not shape
  -More kinetic energy than solid
  -Particules are attracted to one
  -Particles in a liquid are not fixed
  -Particles can move from one plance 
   to another
  ~Particles are close toghether, 
     aren´t tightly
  ~Attached to one another
  ~Particles can slide past another




GASES:
  -Not have definate volume or shape
  -Most kinetic energy
  -Particles are not close
  -Particles can move easoly in any direction
  -Space between particles can decrease or increase
  ~Particles are very far part
  ~The space between the particles can change more
     easily
