      XPost: sci.astro.research       From: jacob@jacob.remcomp.fr              Le 02/06/2017 à 09:16, Poutnik a écrit :       > Thermodynamics generally does not care,       > what time it takes for a system       > to get into the preferred final state.              "Final state" implies time.              Atoms A and B in gas state are inserted into a container in proportion       1:1. The final state is an almost perfect distribution of a mixture of       both gases. We do not expect the gases to appear separated after some       time. That is the accepted final state of a smooth distribution for two       gases in a container at room temperature say.              But is it the final state?              Surely not, since if not given any external energy, the final state of       the mixture could be a separated mixture of frozen A and B at almost       absolute zero. Let's suppose that when freezing, gases A and B do not       mix easily.              Time is always there in all physics. The concept of "final state"       implies time, you see?              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
