mean entropy मीनिंग इन हिंदी

Physicists don't use the word heat to mean entropy.
The OP used the term heat meaning infrared radiation, light is heat only when heat means entropy.
I suppose that when a system of higher entropy is joined with a system of lower entropy that entropy does not move to create a more uniform mean entropy in the joined system.
It would mean entropy would be introduced from a phenomenological POV, which is not my favoriute POV, but if he is willing to spend the time to do a lot of writing, why not let him do that?
