Key Topics to Revise

1

Properties of Gases

  • Gases have negligible intermolecular forces and occupy the entire volume of their container
  • Gas molecules are in constant random motion and collide elastically
  • Volume of a gas = volume of its container (unlike liquids and solids)
2

Boyle's Law (Pressure-Volume Relationship)

  • At constant temperature, volume of fixed mass of gas is inversely proportional to pressure
  • As pressure increases, volume decreases proportionally
  • Graph of P vs V is a hyperbola; PV vs P is a straight horizontal line
3

Charles's Law (Volume-Temperature Relationship)

  • At constant pressure, volume of fixed mass of gas is directly proportional to absolute temperature
  • Volume increases linearly with temperature in Kelvin scale
  • All V-T graphs extrapolate to -273°C (absolute zero)
4

Avogadro's Law and Combined Gas Equation

  • Equal volumes of gases at same T and P contain equal number of molecules
  • Volume is directly proportional to number of moles at constant T and P
  • Combined gas equation: P₁V₁/T₁ = P₂V₂/T₂ combines all three laws
