if there is radiation in the vacuum, then it's not really a vacuum.
Radiation.
No. There is also the transfer of mass. All matter contains energy, thus the movement of mass in vacuum is another method of energy transfer. However, for transferring thermal energy, radiation is the only method that can take place inside a vacuum as it doesn't need particles to travel through where as conduction and convection do.
radiation
Energy transfer takes place by convection (the movement of hot air or other fluids due to diferences in densiity), conduction (transfer of heat through contact - caused by collisions between adjacent particles), or radiation (the transfer of energy by electromagnetic waves such as light or infra-red rays).Radiation requires matter to create and absorb the EM waves, (i.e. you need a hot object to give off the IR waves) but the waves themselves can travel through a vacuum, so do not require matter to transfer energy.
By radiation i think but im not sure :/
No. radiant energy (including heat) can pass though a vacuum.

A vacuum is a space where there is no, or very little matter (ex. air molecules). One example of a vacuum is outer space. Because there is no matter for heat to travel through via convection or conduction, radiation is the only heat transfer that can take place in a vacuum.
radiation, this is the only one that travels in a vacuum
Transfer of heat energy through energy waves is called radiation.
The sun transfer heat through radiationAnswer'Heat' is not transferred. Rather, 'heat' describes the process of transferring energy. So, your question should read, 'How does the sun transfer energy to earth?", and the answer is by radiation.
