Conduction is the type of energy transfer that requires matter to be present. Insulation, convection, and radiation can all take place without matter present.
The type of energy transfer that can take place without matter present is radiation.
The correct answer is radiation. Radiation is a type of energy transfer that does not require the presence of matter. It occurs when energy is directly transferred through electromagnetic waves, such as light or heat. Radiation can take place in empty spaces, vacuum, or even through transparent substances.
