Well, if you have a hammer there certainly is no nail. You didn't understand what I said. Pure energy by itself has no entropy. I was referring to a phrase you made: PaleRider, post 51, “heat, or energy moving from a high entropy state to a lower entropy state.”


As I said earlier, it would have been correct if you said,“heat, or energy of a system moving from a high entropy state to a lower entropy state” You left out the underlined phrase.


Energy can be measured in ergs. Heat is often measured in calories.


So when you refer to energy in a high entropy state, what is the “entropy” of 5 ergs, how does it compare to the “entropy” of 3 ergs. That makes no physical sense. However the following example is the proper way of considering entropy and energy.


What is the entropy of a system containing 1 million O2 molecules at equilibrium in a 1 cm cubed container with a total energy of 5 ergs.


Now that refers to a system, not pure energy. It makes physical sense and can be computed.
