Which statement about the transfer of thermal energy is correct?
Conduction is the transfer of thermal energy through fluids by the macroscopic movement of currents.
Convection can take place in solids if they are heated to a sufficiently high temperature.
Thermal radiation consists of electromagnetic waves and does not require a material medium to travel.
Shiny, silver-coloured surfaces are excellent absorbers of thermal radiation.
