Greetings all,
I hope I'm in the right forum, and someone throw in an idea or two:
I read in "Chaos" where the author mentions an analogy to "change of entropy" as, if one could divide a pool (a 'closed system') in two, and have one half filled with clear water and the other with dyed water, upon removal of the divide, these liquids would mix to a state of equal saturation.
This is a real-world closed system, but does it prove that chaos and entropy only exist in not-so-ideal closed systems?
If one was to assume the following hypothetical 'ideal' system (the criteria are completely impossible):
- There are two fluids of different colour, but with identical molecular mass and electrical charge, i.e. no gravitational or em attraction
- They are divided by a screen which would not cause any turbulence when removed
- This container is in space at zero g and is in no orbit
- It is in total darkness, i.e. none of the fluids will either reflect or absorb any energy (possibly causing turbulence)
- Being in total darkness in space implies absolute zero temperature, which implies that these fluids would be frozen solid, but let's assume they're ideal fluids that can't freeze
Question: Upon removal of the divide, would they still mix and increase entropy? Or would they just hang around because they have no reason to change? Unless someone puts a butterfly in one of the fluids.
I suppose nothing would happen, because this is not a real-world scenario, and therefore it doesn't negate the original real-world analogy, but theoretically it intrigues me.
Just wondering, if anyone wants to comment.
