Question

what is transmission of heat?

Answer 1

Heat is transmitted by conduction when it passes from the hotter to the colder parts of the medium material without any movement of the medium itself and all intermediate parts of the material being warmed in the process. ... Most metals are good conductors i.e they easily transmit heat energy by conduction.

Answer 2

radiation is a method of heat transfer that does not rely upon any contact between the heat source and the heat source and the heated object as is the case with conduction and conversion. heat can be transmitted through empty space by thermal radiation often called infrared radiation of transmission of heat
