I thought this issue was resolved in the '50s, and the thermo
community decided that we would call energy "heat" only if it was in a
state of
maximum entropy, i.e. totally disordered; i.e. energy becomes heat
by becoming disordered and the net momentum goes to zero. Ergo, if it's

heat then there's no momentum to consider. Am I missing something here?


I recall that in the 60's, 70's and 80's Zemansky was adament in
defining heat as some kind of energy that is transferred from an object
at a higher temperature to one of lower tgemperature.
