Question

Identify the process of heat transfer in the following (i) Heat transfer from one end of an iron rod to another. (ii) Heat transfer from one place to another by the actual movement of the fluid particles.

Answer 1

Answer:

Heat transfer takes place by the process of radiation when there are no particles of any kind which can move and transfer heat. So, in an empty space or vacuum heat is transferred by radiation. We shall now study heat transfer by conduction, convection, and radiation in detail.
