Question

What is the meaning of “radiative distribution of entropy”?

Answer 1

The radiation represents a conversion of a body's internal energy into electromagnetic energy, and is therefore called thermal radiation. It is a spontaneous process ofradiative distribution of entropy. Conversely all normal matter absorbs electromagnetic radiation to some degree.

Answer 2

All normal (baryonic) matter emits electromagnetic radiation when it has a temperature above absolute zero. The radiation represents a conversion of a body's thermal energy into electromagnetic energy, and is therefore called thermal radiation. It is a spontaneous process of radiative distribution of entropy.
