Winter, in physics, the macrostate " in question " is the state in which system exists or more accurately spend most of the time, so we (or the system) must choose the macrostate with the highest stat. weight, that is, highest $ \Omega$. Analogy: the extremum of the function (entropy) is a property of the function (system) and not a particular function value of particular argument value | |

making discussing of infinite microstates more explicit

Apr 3, 2019 at 15:31 | comment | added | Acccumulation | @Runlikehell I was trying to get at the infinity problem with my last paragraph, but I think I'll make that a bit more clear. | |
Apr 3, 2019 at 14:59 | comment | added | RenatoRenatoRenato | +1; You may add for completeness that $\Omega$ is actually the volume occupied by all the possible microstates corresponding to the given macrostate, in phase space. I Always found this expression clearer, since both positions and momentum are continuous variables, the number of microstates available would be infinite. | |
