Explanation:
Heat Transfer by Thermal Radiation
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 . All physical substances in solid, liquid, or gaseous states can emit energy via a process of electromagnetic radiation because of vibrational and rotational movement of their molecules and atoms [2]. The intensity of such energy flux depends upon the temperature of the body and the nature of its surface [3]. The radiation occurs at all temperatures, with the rate of emission increasing with the temperature
