"Heat" is the qualitative sensation or quantification of the absorption of energy. "Heat" does not move through empty space - energy moves through empty space.
"Nearly all the energy in Earth's atmosphere comes from the sun. Energy travels to Earth as electromagnetic waves, a form of energy that can move through the vacuum of space."-Science Explorer
Some waves do. Both electromagnetic waves and gravity waves are able to move through empty space - and to transport energy through empty space.
Instead of using Wiki Answers to complete your homework, why don't you actually look through your book?
Energy in the form of electro magnetic waves. Some examples are light,heat,UV etc
Any form of energy that requires a physical medium to move from place to place could not propagate in empty space. An obvious example is sound energy.
Energy and information.
Gravitational (-GmM/r) and Electromagnetic (hf=hc/r) Energy.
Radiation is the only process because it has infra red waves which has no medium and can travel through space.
Conduction through solids, convection through liquids and gases, and radiation through empty space.
space is a vacuum, and sound can't move through a vacuum.
The energy of the high energy molecules used for every time 2 high energy electrons move down the chain causes the H+ ions to move to the matrix.
It is used to pump H+ through a membrane and into the intermembrane space.
Just as light energy moves in the form of electromagnetic waves
Compression waves, such as sound, cannot move through space due to the lack of a medium. Transverse waves, such as light and radiation, can move through a vacuum such as space. This is related to Einstein's theory of relativity, in which he states that Mass and Energy are the same thing. Essentially, transverse waves, which move at the speed of light, are moving fast enough to metaphorically be their own medium, as stated by the equation E=MC2 (Energy traveling at the speed of light is what we call a photon, which is a very hard concept to explain. The best I can do off the top of my head is that it's almost like it's matter and energy at the same time). Since the energy is it's own medium, the energy can travel through a vacuum, where there is no other medium to support it.
They move through the energy cycle.
