Why can heat only be transferred through a vacuum by radiation, and not conduction or convection? (3)

Heat transfer by conduction and convection works by particles colliding and transferring energy, as there are no particles in a vacuum heat transfer can only occur by radiation. This is because radiation involves electromagnetic waves, not particles, and is therefore able to transmit heat across a vacuum.
