Answer :
Answer:
The answer is In radiation, energy can propagate in a vacuum.
Explanation:
Radiation, convection and conduction are forms of heat and energy transfer, but they differ in that the radiation phenomenon can propagate energy not only in material media but also in the form of electromagnetic waves or subatomic particles through vacuum, while convection and conduction can only be propagated by a material medium.
Radiation is different from conduction and convection in the transfer of heat.
In conduction heat is transferred by direct contact, in convection heat is transferred within the fluid and in radiation, heat is transferred through electromagnetic waves without the need of involving any particles.
Thus, radiation uses electromagnetic waves to conduct heat without any involvement of particles, other than conduction, and convection which need some matter to transfer heat.
