Thermal Processes

Students should be able to:

1. show an understanding that energy is transferred (by heating) from a region of higher temperature to a region of lower temperature until thermal equilibrium is achieved between the two regions
2. describe, in microscopic terms, how conduction occurs in solids (via vibration of atoms/molecules and movement of electrons)
3. describe, in terms of density changes, how convection occurs in fluids
4. explain that energy transfer by electromagnetic radiation does not require a material medium and that this rate of energy transfer to/from a body is affected by its:
   1. surface colour and texture
   2. surface temperature
   3. surface area
5. apply the concepts of conduction, convection and radiation in everyday examples.
