Question

Explain the three modes of transfer of heat.

Answer 1

Three modes of heat transfer are
(a). Conduction involves the transfer of heat from the hot end to the cold end from particle to particle of the medium.
(b). Convection is the transfer of heat from one body to another by the actual movement of the particles of the medium
(c). Radiation is the transfer of heat from one body to another without the need of an intervening material medium
