Heat transfer is a type of energy transfer which takes place because of temperature difference from one system to another.
• Heat transfer is thermal energy in transit because of spatial temperature gradient.

In thermodynamics we deal with.
(i) amount of heat transfer and amount of work transfer as system goes from one state to another (ii) only with the end states during a process. (iii) equilibrium phenomenon..
in heat transfer we deal with (i) rate of heat transfer (& J/8)
(ii) the time taken by the system as it goes from state 1 to state 2
!!!) the temperature distribution or temperature profile inside the system.. live the mode of heat transfer (conduction. convection, radiation) Iv) non equilibrium position.
