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
