The type of energy transfer that can take place with little or no matter present is radiation.
Radiation is the type of thermal energy transfer that can take place with little or no matter present. This process allows heat to travel through empty space by electromagnetic waves such as light.
Electromagnetic Energy does not require matter to be transferred...that is why it can travel through the vacuum of space.
Some forces, such as gravity or the electrostatic force, can act without direct contact. If a force is applied over a certain distance (such as, when an object falls), work is done, i.e., energy is transferred. Ah, but what is direct contact? One electrostatic field pushing against another? If I touch something, it is the electrostatic fields pushing against each other. There is no direct contact!
No, conduction requires the presence of matter for energy to be transferred. Energy transfer by conduction occurs through direct contact between particles in a material, so without matter, conduction cannot take place.
No, the movement of matter requires energy transfer. Energy is needed to overcome any resistance to movement, such as friction or inertia. Without energy transfer, matter would remain stationary or at rest.

Radiation does not require matter.
Radiation can go right through empty space.
False. EM Waves do not transfer matter, they transfer energy.
The transfer of light energy to particles of matter is called absorption. When light interacts with matter, the energy from the light is absorbed by the particles, causing them to gain energy and potentially change their properties.
