4.6 describe how energy transfer may take place by conduction, convection and radiation

There are three basic ways energy can transfer from place to place: conduction, convection and radiation.

Conduction: Conduction is the transfer of energy through substance mainly metals, without the substance itself moving. They transfer energy through molecular vibration or free electron diffusion.

Convection: Convection is the transfer of energy by means of fluids (liquids or gases) by the movement of molecules.

Radiation: Radiation is the transfer of energy by means of wave. It doesn’t need any medium to flow through.
