Conduction, convection and thermal radiation are the primary mechanisms for thermal energy transfer
Quantitative analysis of energy transferred by radiation as a result of the emission of electromagnetic waves from the surface of a body, which in the case of a black body can be modelled by the Stefan-Boltzmann law
A phase change represents a change in particle behaviour arising from a change in energy at constant temperature
The concept of apparent brightness b
Luminosity L of a body
The emission spectrum of a black body and the determination of the temperature of the body using Wien’s displacement law

Explain the physical differences between solids, liquids, and gases in terms of the molecular model.
Explain the physical differences between solids, liquids, and gases in terms of the molecular model.
Understand that the particles in a solid are tightly packed together, while the particles in a liquid are more loosely packed, and the particles in a gas are very far apart.
Understand that the forces of attraction between particles are stronger in a solid than in a liquid, and weaker in a gas.
