The Particulate Nature of Matter (Chapter 7)

• Matter


  -Occupies space

  -Has mass

  -Exists as a solid/liquid/gas
• Particulate model of Matter for Solid

  Motion: Vibrates at their fixed position

  Attractive forces between particles: Very strong

  Arrangement: In a regular manner

  Distance between particles: Close together
• Particulate model of Matter for Liquid

  Motion: Move about within confined space

  Attractive forces between particles: Moderately strong

  Arrangement: In a irregular manner

  Distance between particles: Quite close together
• Particulate model of Matter for Gas

  Motion: Move at high speed freely at everywhere

  Attractive forces between particles: Very weak

  Arrangement: In an irregular manner

  Distance between particles: Very far apart
• Diffusion


  Diffusion is the process where particles move from a region of higher concentration to a region of lower concentration until evenly distributed.
