Changing state

Learning objectives:

  • Describe changes of state in terms of melting, boiling, evaporation, freezing, condensation and sublimation
  • Explain changes of state in terms of the kinetic theory, including the interpretation of heating and cooling curves
  • Describe the effects of temperature and pressure on the volume of a gas
  • Explain, in terms of kinetic particle theory, the effects of temperature on the volume of a gas
