I disclaim any relevant learnedness. So it is with no angst that I parse
this paragraph to mean.

"There are books that mention properties called
N
E
V

"These books also mention processes or qualities or states  called
constant
free expansion
change
microcanonical ensemble.

"I am not sure what I am intended to understand when each of
these words is used.   Please help me understand.
I take it that you are both smart, and more certain of the appropriate
definitions."

And now my conclusion: if one reads such a book: a book that does not
 adequately define its terms as and when needed, then the only appropriate
 course of action is to consign it to the round file.
