Too often thermodynamics is based upon the shuffling of partial derivatives, which is not necessarily embedded in profound logic

Like the second law, entropy is poorly understood. Not only does it require clarity, but we also must learn its limitations
The second law wrongly used to explain so much. The reality is that it is limited to systems that simply do not exist here on Earth, and is certainly not applicable to any useful system.

More often then not lost work is the energy lost by an expanding/useful system into the surrounding atmosphere.
The internal energy of a system is misunderstood. It also shows mankind's tendancy to complicate the simple.
We shall discuss why currently accepted kinetic theory is
problematic and how to fix it. It is in three parts.
We shall introduce you to the concept of negative work that
being the displacement of our atmosphere by a volume of nothing, against a gravity
We shall discuss the misundertstandings associated with the 19th century idealistic cycle that being the Carnot cycle
We shall discuss how walls influence what we witness thus putting limitations upon kinetic theory, ideal gas law etc
To bad Maxwell and or Clausius did not realize why "Lost Work" occurs in expanding systems
We shall discuss Maxwell's demon, and it limitations in
context of walls and our new thermodyanmic perspective
We shall discuss the misundertstandings associated
with the 20th century great
Currently part of statistical, but should become its own blog
We shall discuss the fact that probabilities give results
and not reasons
We shall explain the difference bewteen isobaric
and isometric specific heats of gases in terms of work
We discuss why a gaseous sytem can only use 2/3 of
its total energy to perform work.
We will show that Boltzmann's constant is not universal
Thermodynamic myths/fallacy
3) A system loses its ability to do work as its entropy increases. The reality is: The ability of
a system to do work diminishes as its thermal energy density decreases. This holds for both thermal radiation and/or mechanical energy
i.e. pressure: Note when pressure of a gaseous system equals that of its surroundings then the system can no longer power anything
via mechanical force.
4) Entropy controls heat transfer: Again a definition of entropy would help. The reality is that thermal energy
(heat) tends to flow from regions of high thermal energy densities to cooler one, i.e. net flow is hot to cold. Sounds like common
sense!
