  1. KINETIC THEORY OF MATTER Objectives: (a) describe solids, liquids and gases in terms of the spacing, ordering and motion of atoms or molecules; (b) describe a simple kinetic model for solids, liquids and gases;

  2. KINETIC THEORY OF MATTER Outcomes ALL MUST Be able to describe solids, liquids and gases in terms of the spacing, ordering and motion of atoms or molecules. Be able to describe a simple kinetic model for solids, liquids and gases;

  3. 3 STATES OF MATTER SOLID LIQUID GAS

  4. SOLIDS • Fixed shape and volume • Normally hard and rigid • Large force needed to change shape • High density • Incompressible

  5. Model of Solids • Closely packed together • Occupy minimum space • Regular pattern • Vibrate about fixed position • Not free to move about

  6. LIQUIDS • Fixed volume but no fixed shape • High density • Not compressible

  7. Model of Liquids • Occur in clusters with molecules slightly further apart as compared to solids • Free to move about within confined vessel

  8. GASES • No fixed shape or volume • Low density • Compressible

  9. Model of Gases • Very far apart • Travel at high speeds • Independent and random motion • Negligible forces of attraction between them
