Step-by-step explanation:
There are three modes of heat transfer; conduction, convection and radiation.
Conduction refers to the transfer of heat without the actual movement of the particles of matter.
Convection is the transfer of heat by the actual movement of the particles of matter.
Radiation is the transfer of heat without a material medium.
Hence the three modes of heat transfer differ in the actual mechanism by which heat energy is transferred as shown above.
