Heat transfer from a body with a high temperature to a body with a lower temperature, when bodies are not in direct physical contact with each other or when they are separated in space, is called heat radiation [1], as schematically shown in Fig. 3.1.All physical substances in solid, liquid, or gaseous states can emit energy via a process of electromagnetic radiation because of vibrational and
This is called heat transfer. (Remember, we learned that energy transfer is when energy moves from one thing or place to another, but the energy type stays the same).
