::::::I didn't have that thought in mind. Not concerned about it yet.[[User:Chjoaygame|Chjoaygame]] ([[User talk:Chjoaygame|talk]]) 03:42, 18 December 2020 (UTC)
:::::::You said: "I am not too worried about this. I guess that increases and decreases can be stepwise or gradual and continuous." But you said you had a problem with the statement "Entropy does not increase indefinitely".
:::::::You quoted Chetvorno: "But the title of the article is not Irreversibility, it is Entropy, the introduction gives readers no idea of what that is." This is not true, as seen by the statement "In thermodynamics, entropy is a numerical quantity that shows that many physical processes can go in only one direction in time.". The only way thermodynamic entropy presents itself to our senses and measuring instruments is through its change. Thermodynamic entropy cannot be experimentally measured, only its change.
:::::::Regarding my statement "Any state, disequilibrium or not, has a macrostate, and an associated set of microstates, .". Yes, I have to amend that statement. It holds for cases where, e.g. the pressure and temperature for each type of particle are defined functions of space and time ([[local thermodynamic equilibrium]]). Now entropy density can be defined and total entropy can be said to decrease, assuming we can talk about the rates of energy and entropy tranfer between two equilibrated systems in contact and almost in equilibrium with each other. But the question is, how does this apply to an introductory article? Can we use the words "Entropy does not increase indefinitely" as an introductory statement, knowing that it is flawed? I think the verbal gymnastics we have to go thru to keep things rigorous but simple are almost overwhelming in this case. [[User:PAR|PAR]] ([[User talk:PAR|talk]]) 07:36, 19 December 2020 (UTC)
