1-1C Thermodynamics deals with the amount of heat transfer as a system undergoes a process from one equilibrium state to another. Heat transfer, on the other hand, deals with the rate of heat transfer as well as the temperature distribution within the system at a specified time.
1-2C (a) The driving force for heat transfer is the temperature difference. (b) The driving force for electric current
