Conduction Heat Transfer(Mechanism and definition)

Conduction Heat Transfer(Mechanism and definition)

 Conduction Heat transfer is the  transfer of thermal energy between adjacent molecules in a substance  due to temperature gradient. Conduction takes place in all forms of matter like solids,liquids, and gases. 

           In solids conduction heat transfer is due to combination of vibrations of  molecules in the lattice and the energy transport by free electrons.

Example for conduction heat transfer is  Heating of a rod with the help of a burner.

In liquids and gases it takes place by means of collision and diffusion of molecules during their random motion.
