| − | Heat transfer is a boundary phenomenon that arises from the difference in temperature of two systems. On the other hand, the work transfer is the transfer of work in the form energy from the system to the surroundings or vice versa due to other property differences. This includes all the displacement, electrical, and other mechanical works. Similar to heat transfer, work transfer is also a boundary phenomenon. In other words, heat transfer and work transfer are both energy interactions where the former is due to the temperature difference in the system and surroundings | + | Heat transfer is a boundary phenomenon that arises from the difference in temperature of two systems.
