<div>Greg,</div>

<div>The energy doesn't change. The bond energy in the water is constant regardless of pressure.</div>
<div> </div>
<div>The cavitation issue is different. It is a phase change phenomenon, not a chemical change one.</div>

Since we are speaking input air, I thought I might ask a somewhat
related question.
Water gas shift. I know there are many that have talked about this,
and I understand the basics.
However, here is the question.
At what negative pressure ( negative in/wc) does the shift move down
the temperature scale, to the point of being within the 1000 - 1200 c
area ?
We all know that propeller cavitation produces steam in water that is
10 c (or there abouts), I have to assume (not being a chemist) that
the same negative pressure effect would also apply to other principals
when dealing with water.
