It doesn't it can't.... space is a gravitation area filled with gravity. only cold air flows through space because of the wicked temperatures of some planets. You only feel heat from the planets that have the heat because they keep their heat inside due to the greenhouse effect
heat transfers threw induction
The transfer of heat energy through empty space is called radiation.
Radiation
The Transfer of heat through space.
Radiation
it can be transferred through metal...and glass...
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 through open space without the use of any medium is called radiation. Radiant heat travels in electromagnetic waves and does not require a medium to carry it. Examples include the heat we feel from the sun or a fireplace.
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 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.
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.
The type of heat transfer that travels through space in electromagnetic waves is called radiation.
