Answer 2

Answer:

Transfer of heat :

Heat transfer is a discipline of thermal engineering that concerns the generation, use, conversion, and exchange of thermal energy (heat) between physical systems. The three modes of heat transfer are conduction, convection and radiation.

(i) Conduction is the mode of heat transfer within a body or between two bodies in contact, from a region of high temperature to a region of lower temperature without the migration of the particles of the medium.

(ii) Convection is the mode of heat transfer from one part of a fuid to another by the migration of the particles of the fluid.

(iii) Radiation is the mode of heat transfer by electro magnetic waves/ quanta.
