Answer:

Both conduction and convection need matter to transfer thermal energy.

Conduction involves collision of particles, while convection involves the movement of a liquid or gas.

Explanation:

There are three ways in which heat is transmitted:

  1. By Conduction, when the transmission is by the direct contact (through collisions).

   2. By Convection, heat transfer in fluids making a current created by less dense fluids floating and more dense fluids sinking (like water or the air, for example).  

  3. By Radiation, by the electromagnetic waves (they can travel through any medium and in vacumm)

Therefore, both conduction and convection need matter to transfer thermal energy (unlike radiation).
