#chemistry #Physics people of #mastodon can you help me understand if this question I've had has an answer.
Here is my attempt at asking my question:
Is there a reaction/phenomenon that *seems* to violate the laws of entropy but actually doesn't? For example, you have substance A then you place a droplet of substance B on it and it diffuses/spreads/mixes and later (after some time) it seemly starts pulling together until it's again a single droplet of substance B (as if time itself had rewinded tenet style) such that if I took a video of this reaction and later on gave you the frames/pictures of that video, you would not be able to with 100% certainty put the frames together in the original order (since you can't tell which frames corresponds to the original droplet of B in A and which one corresponds to when B clumped up after having first diffused). What is this reaction?
@zpartacoos Theoretically, because of stochastic nature of difusion, there might be a feaction of second where the substance B spontaneously forms a clump efter being completely dissolved. The chance of it happening is astronomically small but never zero. There is a cool book I've read related to your question called "Second Law". I recommend it even though it's kind of old.
