Re: dW turns into dQ

This might be compared to asking, in F=mA, "if F includes the sum of
electrical, gravitational, etc forces and only their (vector) sum matters
for calculating A, why the partitioning?" Of course it is because this
partitioning is our way of enabling the calculation of that sum, but the
resulting A wouldn't care if you used a different partitioning (taxonomy
of F) so long as you applied the same vector sum.

Yes, Bob, but not quite. As far as dE goes mox nix. BUT dQ also changes
the entropy! So it is requisite to at least consider some sort of
partition between dQ and dW -- surely so in the cases of reversible actions.
