Key Topics to Revise
1
Temperature and Heat
- Temperature is a measure of hotness or coldness of a body - it's the average kinetic energy of molecules
- Heat is energy transferred between systems due to temperature difference
- Temperature is intensive property (independent of mass), heat is extensive property (depends on mass)
2
Thermal Expansion
- All materials expand when heated and contract when cooled (except water between 0-4°C)
- Linear expansion: increase in length, Area expansion: increase in surface area, Volume expansion: increase in volume
- Coefficients of expansion are material-dependent properties
3
Specific Heat Capacity and Calorimetry
- Specific heat capacity is the heat required to raise temperature of unit mass by 1K
- Heat capacity depends on mass, specific heat capacity is independent of mass
- Molar heat capacity relates to one mole of substance
4
Change of State and Latent Heat
- Phase changes occur at constant temperature with heat absorption/release
- Latent heat is energy required to change state without temperature change
- Melting point and boiling point are characteristic properties of substances
