Presentation Transcript

  1. Hand-in a paper with one of these explained: • Use the KMT to explain why • A balloon placed in the freezer would shrink • A balloon in the microwave would pop.

  2. Changes in State Phase Changes

  3. Explainthe process of melting, freezing, sublimation, and deposition in terms of KMT. • Usethe KMTto explain the processes of evaporation and condensation. • Include: exothermic, endothermic • Additional KEY Terms • Characteristic Property Vapour

  4. Melting or Fusion (s) (l) • Solid is heated (energy absorbed - endothermic). • Energy is utilized to reduce IMFs. • Particles move more freely - liquid. • Characteristic Property (melting point) • unique to each substance.

  5. Vaporization (l) (g) • Energy absorbed (endothermic) further break IMFs • Particle motion increases - gases form • Characteristic Property (boiling point) There are two types of vaporization: evaporation and boiling

  6. 1. Boiling- liquid particles at the bottomgiven enough energy to overcome IMFs - vapourreleased. 2. Evaporation: liquid particles on the surfacehave enough energy to overcome IMFs- vapourreleased.

  7. Particles on the surface have fewer IMFs than other particles.

  8. Condensation (g) (l) • Kinetic energy of the particles decreaseas it cools. • Particles slow down, IMFs take hold. • Energy released (exothermic) to surroundings.

  9. Freezing or Solidification (l) (s) • Particles continue to lose energy (exothermic). • Particle motion decreases further. • IMFsincrease and hold stronger. • Particles arrange into unique solid pattern. • Crystalline or amorphous

  10. Sublimation (s) (g) Deposition (g) (s)

  11. decrease IMFs decrease Kinetic Energy decrease particle motion increase particle motion increase Kinetic Energy increase IMFs

  12. CAN YOU / HAVE YOU? • Explainthe process of melting, freezing, sublimation, and deposition in terms of KMT. • Usethe KMTto explain the processes of evaporation and condensation. • Include: exothermic, endothermic • Additional KEY Terms • Characteristic Property Vapour
