Question

Difference thermodynamics and heat transfer

Answer 1

Thermodynamics and Heat Transfer both are part of thermal engineering and each has its own meaning and importance. Both deals with heat and energy then, one might ask, what is the real difference between the two subjects ? i.e. Thermodynamics and Heat Transfer

"Thermodynamics" deals with the amount of energy in form of heat or work during a process and only considers the end states in equilibrium. It will not give information about how long it will take to reach to the final state in equilibrium. While,
.
."Heat Transfer" deals with the rate of energy transfer thus, it gives idea of how long a heat transfer will occur? Heat transfer deals with time and non equilibrium phenomena. Heat can only transfer when there is a temperature gradient exists in a body and which is indication of non equilibrium phenomena.
