Quizplus · Accepted Answer

In the vacuum of space, convection and conduction are not effective because they require a medium (like air or a physical object) to transfer heat. Evaporation requires a liquid to turn into gas, which is not practical or efficient in the vacuum of space. Radiation, however, does not require a medium; it is the process by which heat is emitted as electromagnetic waves and can effectively be used to get rid of unwanted heat from spacecraft.
