Which method of energy transfer does not involve the movement of matter?

Answer 1

Energy transfer takes place by convection (the movement of hot air or other fluids due to diferences in densiity), conduction (transfer of heat through contact - caused by collisions between adjacent particles), or radiation (the transfer of energy by electromagnetic waves such as light or infra-red rays).

Radiation requires matter to create and absorb the EM waves, (i.e. you need a hot object to give off the IR waves) but the waves themselves can travel through a vacuum, so do not require matter to transfer energy.

Answer 2

the method of transferring heat does not rely on the movement of molecules is conduction because solids transfer heat through conduction.
