Radiation, or it simply moves around within the original medium..
The only form of heat transfer that can occur across empty space is radiation. Radiation does not require a medium to transfer heat and can travel through the vacuum of space, such as sunlight reaching the Earth.
The transfer of heat energy through empty space is called radiation.
Heat is the transfer of thermal energy.If it is across empty space, then it's radiated heat.If through matter, then heat conduction.There is also convection, which is gas molecules gaining the heat energy, then the gas moves around, carrying the heat with it.
No, heat does not travel through empty space by conduction because conduction requires particles to transfer heat energy from one molecule to another. In empty space, heat transfer occurs through radiation, where energy is transferred via electromagnetic waves.
Empty space is a good insulator because it doesn't contain molecules to transfer heat through conduction or convection. With no particles to carry heat energy, empty space acts as a barrier for heat transfer, making it an effective insulator in vacuum conditions.

Yes. That's mainly how the warmth of the sun gets here.

Heat transfer through empty space is known as radiation. It does not require a medium (such as air or water) for heat to travel and can occur in a vacuum. This type of heat transfer is how the sun's energy reaches us on Earth.
Heat transferred across empty space is called radiation. Radiation does not require a medium to transport heat and can travel through a vacuum. It is how energy from the sun reaches the Earth.
If you are asking about a box filled with a gas, then heat transfer can modeled as conduction through a solid. The requirement would have to be no fluid flow (obviously there is movement at the micro level), and the conductive heat transfer coefficient would be very low.Convection heat transfer is dependent on that conductive heat transfer coefficient of the liquid and is based on something called the Nusselt number.If you are asking about heat transfer through a completely void space, then heat would travel by means of radiation.
Radiation
Heat transfer between materials that are touching is called conduction, where heat is transferred through direct contact. Heat transfer through empty space is called radiation, where heat is transferred through electromagnetic waves. Heat transfer by the movement of warm particles is called convection, where heat is transferred through the movement of liquid or gas.
Radiation waves can travel in space, which is are later converted into heat when it hits matter.
