Which best describes radiation heat transfer?
A
the transfer of heat due to circulation which is based on changing densities
B
the transfer of heat energy from one solid that is in contact with another solid
C
the transfer of heat from one location to another through the movement of fluids
D
the transfer of heat through electromagnetic waves which does not involve the movement of matter
D
the transfer of heat through electromagnetic waves which does not involve the movement of matter
D
the transfer of heat through electromagnetic waves which does not involve the movement of matter
The correct answer is D. Radiation heat transfer is the transfer of heat through electromagnetic waves, and it does not involve the movement of matter.
To arrive at this answer, you can eliminate options A, B, and C based on their descriptions. Option A describes convection, the transfer of heat due to circulation based on changing densities. Option B describes conduction, the transfer of heat energy from one solid to another through direct contact. Option C describes convection as well, the transfer of heat from one location to another through the movement of fluids.
Option D is the only one remaining, and it describes radiation heat transfer accurately. Radiation is the process by which heat is transferred through electromagnetic waves, such as the way the Sun transfers heat to the Earth.
