malform11 Posted March 8, 2018 Report Posted March 8, 2018 Entropy It is falsely stated that matter exclusively strives towards disorder, and that everything in the universe is slowly becoming less orderly. Note that (disorderly) mixtures of liquids will separate over time, strive towards order. Shake well is on the side of liquid containers. Paint must be shaken or stirred. With liquids, gravity does the work of creating order. The FLAW in the conclusion of the famous entropy experiment.: Balls are placed in a box, with an open top. Half of the balls are black, the other half are white, placed separate from each other. As the box is shaken the white and black balls stir together, and appear that they will not separate again, based on HUE. Although they are of two different hues, the balls are the same material, same size, shape, and density. The box does not recognize hue. Within the box, all the balls are essentially identical, and should naturally group rather than separate. The experiment actually demonstrates nature striving for order, by like elements grouping together. There can be no order without like elements grouping together... If in the experiment balls were suspended in a liquid, and a light were to shine on them, the black balls would absorb more light, become warmer, separate and rise above the white balls. Quote

Your post seems to betray a misunderstanding of entropy and the 2nd Law of Thermodynamics. What this actually says is that any irreversible or spontaneous thermodynamic process proceeds with a net increase in entropy. That does not preclude an increase in order in part of the thermodynamic system, so long as more disorder is created elsewhere in the course of the process, to compensate for this. An example is the freezing of water. Ice forms, which is a more highly ordered (lower entropy) structure than liquid water. However, Latent Heat is also released when ice forms and this low temperature heat is exported to the surrounding environment. Since entropy change, ΔS = ΔQ/T (energy change divided by temperature), low temperature heat has more entropy than high temperature heat. Thus, even when an orderly structure such as ice forms, the entropy of the whole thermodynamic system increases. Edited March 8, 2018 by exchemist sanctus 1 Quote
