How does a person take into account in practice the different ability of bodies to absorb radiation energy?

People have long used the different ability of bodies to absorb radiation energy, for example, teapots and pans are released with a mirror surface (then they emit less heat), the surfaces of airplanes and helicopters are painted with silver paint so that they are less heated by the sun (they better reflect heat).

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
