Three states of matter

• Three states of matter

  • Solid
  • Liquid
  • Gas
• Particle model

  • Solid=close together and regular pattern
  • Liquid=close together but a random arrangement
  • Gas=far apart and move quickly in all direction
• What take place at melting point

  • Melting and freezing
• What takes place at boiling point

  • Boiling and condensing
• Melting and boiling points

  • The stronger the force of attraction between particles is the higher the melting and boiling points
• Limitations of particle model

  • No forces
  • All particles are spheres
  • Spheres are solid
