Question

A

B

WHY is radiation the only type

of heat transfer that can pass

through a vacuum?

because conduction and convection both

need matter in order to transfer heat

because radiation, convection, and

conduction are all the same thing

Answer

Radiation is the only type of heat transfer that can pass through a vacuum because it does not require matter to transfer heat, unlike conduction and convection.

Heat transfer occurs in three ways: conduction, convection, and radiation. Conduction and convection both require matter to transfer heat. Conduction occurs when heat is transferred through a material by the collision of its atoms or molecules. Convection occurs when heat is transferred through a fluid by the movement of its particles. Radiation, on the other hand, is the transfer of heat through electromagnetic waves, which do not require a medium to travel through. Therefore, radiation is the only type of heat transfer that can pass through a vacuum.
