Presentation Transcript

  1. Particle Theory of Matter(See handout for a complete list) • Space: The spaces between the particles are very large compared to the sizes of the particles themselves. • Speed: The particles in matter are in constant motion. • Stickiness: The particles in matter attract one another.

  2. States of Matter • Physical state is based on • The nature of the bonds between the particles (potential energy, “stickiness”) • The motion of the particles (kinetic energy, “speed”)

  3. Solids • Rigid • Definite shape • Definite volume

  4. Solids • Stickiness of bonds limits particle motion • Particles vibrate in relatively fixed positions (low speed)

  5. Solid State – 4 particles

  6. Solid State – Multiple Particles

  7. Liquids • Definite volume • Takes shape of container

  8. Liquids • Stickiness of the bonds is lower than in solids • Particles have more speed than in solid state

  9. Liquid – 4 particles

  10. Liquid – Multiple Particles

  11. Gases • No definite shape • No definite volume • Takes shape of container

  12. Gases • Stickiness between particles is zero • Greater speed than in solid and liquid states

  13. Gas – 4 particles

  14. Gas – Multiple Particles
