::The impossibility of a [[perpetual motion machine]] that keeps going with constant energy illustrates this. But notice how some deny, or won't admit, its impossibility. If you agree this type of [[perpetual motion machine]] is impossible, then why do you think it is impossible, if not due to the Second Law?--[[User:Aschlafly|Andy Schlafly]] 00:33, 15 June 2012 (EDT)

:::Why do you ignore half of what I'm trying to say? I do agree with almost everything you just wrote (although even phase changes are thermodynamically irreversible because they require heat transfer or some other irreversible factor). But that doesn't change the fact that individual objects/materials/subsystems can have decreases in entropy (increases in "order") even though overall net entropy increases. That is why you can't use the argument "everything becomes more disordered" as an argument against evolution. --[[User:Randall7|Randall7]] 20:37, 15 June 2012 (EDT)
