Four rods made of different metals are attached to a heated central block. At the outer end of each rod, a small pin is held in place by a dab of candle wax.
State the name of the process by which thermal energy is transferred through the metal rods.
Explain how this experiment shows which metal is the best thermal conductor.
State the main type of electromagnetic radiation that transfers thermal energy from the Sun to the Earth.
State the process of thermal energy transfer that can travel through a vacuum.
Emergency survival blankets are made of a highly reflective, shiny silver-coloured foil.
Explain how this shiny surface helps to keep a person warm by reducing thermal energy loss.
