WebApr 5, 2024 · Vacuum is created in a region of closed space, by extracting all the air in the space through vacuum pump equipment. The processes conduction and convection take place with the help of the molecules, they are not possible in vacuum since there is no existence of any molecules to transfer the heat. WebRadiation is the transfer of heat through electromagnetic waves through space. Unlike convection or conduction, where energy from gases, liquids, and solids is transferred by the molecules with or without their physical movement, radiation does not need any medium (molecules or atoms). Energy can be transferred by radiation even in a vacuum.
