That refers to radiation.
Radiation is the heat transfer method that does not require a medium. It can occur through empty space, such as from the sun to the Earth, without the need for a material medium.
The only way to transfer heat in a vacuum is through radiation. Heat transfer by convection and conduction require a medium, such as air or a solid, to transfer energy. In a vacuum, radiation is the only method by which heat can move.
Infrared radiations. They do not require any medium. So they don't heat any medium. They don't even heat the air through which they pass.
Conduction and convection are prevented by a vacuum because there are no particles to transfer heat through direct contact or movement. Radiation is the only method of heat transfer that can occur in a vacuum, as it does not require a medium to propagate the heat.
The transfer of heat energy through empty space is called radiation.
Radiation is the heat transfer method that does not require a medium. It can occur through empty space, such as from the sun to the Earth, without the need for a material medium.
Both conduction and convection require an intervening medium, but convection requires the medium to be able to move.

Radiation is a method of heat transfer that does not require a medium to travel; it can occur even in a vacuum. This is important because it allows heat to be transferred over large distances, such as from the sun to the Earth, and can also be used in various engineering applications like in thermos bottles.
Radiation is the type of heat transfer that does not require a solid, liquid, or gaseous medium. It can occur through vacuum or transparent mediums such as air or glass.
Radiation is a type of heat transfer that doesn't require a medium to travel. It can occur through vacuum or space as electromagnetic waves carry the heat energy from a hotter object to a cooler one.
Radiation is the energy transfer process that does not require the presence of molecules to transfer heat. It can occur through empty space and does not require a medium to carry the heat. Examples include heat transfer from the sun to the Earth and infrared radiation emitted by objects.
Heat transfer by means of radiation doesn't heat the medium. In fact, radiation doesn't even require a medium in order to work. Strictly speaking, convection doesn't heat the medium either. Convection transfers heat by moving the medium around. Of course, heat also spreads throughout the medium by conduction while the convection is going on.
