Key Topics to Revise
1
Temperature and Heat
- Temperature is a measure of average kinetic energy of molecules/atoms in a substance
- Heat is energy in transit from higher to lower temperature objects
- Temperature determines thermal equilibrium state between two bodies
2
Ideal Gas Equation and Absolute Temperature
- Gas laws: Boyle's (PV = constant), Charles' (V/T = constant), Gay-Lussac's (P/T = constant)
- Ideal gas equation: PV = nRT, where R = 8.31 J K⁻¹ mol⁻¹
- Absolute temperature scale based on ideal gas behavior
3
Thermal Expansion
- Linear expansion: increase in length due to temperature rise
- Areal expansion: increase in surface area due to heating
- Volume expansion: increase in volume due to temperature change
4
Specific Heat Capacity
- Specific heat: heat required to raise temperature of unit mass by 1°C
- Water has highest specific heat (4186 J kg⁻¹ K⁻¹) among common substances
- Molar specific heat: heat per mole per degree temperature rise
