GCSE Chemistry - Kinetics and Diffusion

Chemistry Section 1


1.1


N/A Solids Liquids Gases

Arrangement of Close together Close together Far apart
particles Regular Pattern Random movement Random movement

Movement of Low kinetic energy Med kinetic energy High kinetic energy
particles Vibrate on spot Move over each Move quickly in all
other directions


1.2
- Solid to Liquid - melting
- Liquid to solid - freezing
- Liquid to gas - evaporation/boiling
- Gas to liquid - condensation
- Gas to solid - deposition
- Solid to gas - sublimation


- Solid to liquid - heat required
- Liquid to solid - cooling required
- Liquid to gas - heat required
- Gas to liquid - cooling required
- Gas to solid - cooling required
- Solid to gas - heat required


- Solid to liquid - lose regular pattern, gain kinetic energy
- Liquid to solid - gain regular pattern, lose kinetic energy
- Liquid to gas - particles stop touching, gain huge amounts of kinetic energy
- Gas to liquid - particles touch, lose kinetic energy
- Gas to solid - gain regular pattern, lose lots of kinetic energy
- Solid to gas - lose regular pattern, gain huge amounts of kinetic energy
