Can entropy decrease11/27/2023 ![]() I am not a physicist so I don't know for sure how that plays into entropy calculations but think it is considered a spontaneous increase in entropy. ![]() ![]() It sounds like you're asking if it's possible for all the random movements of particles through pure statistical chance to to result in one of the infinitesmal combinations of particle positions where the particles are segregated instead of one of the infinitely greater combinations where the particles are not segregated? Yes, it's mathematically possible but you will never see it in your lifetime, or anyone else's, or even the universe's lifetime. Therefore, can there EVER be any spontaneous fluctuations that lowers the entropy (segregate the content) of such an isolated system? However, such a chamber is often represented as pebbles on a board: But pebbles remain in the segregated state indefinitely, whereas gas particles always homogenize spontaneously and always resist segregation as discussed. The more we try to segregate, the harder it gets showing that this separation will never happen spontaneously. This can be verified experimentally by trying to separate the gas into distinct regions, one of high pressure and another one with vacuum. ![]() If so, the two states do not actually represent the same macro-state, hence we will never expect particles in a homogeneous gas chamber to spontaneously segregate. I understand that, were all the gas particles concentrated in one corner, the entropy of the chamber will be lower than the entropy of the same chamber but homogenized. Consider the simplest such system: a gas-filled chamber. ![]()
