| Apr 1, 2020 at 11:27 | comment | added | electronpusher | @AnthonyP Yes an important subtlety, but that can be resolved by making a point to define what is the system, surroundings, and "universe" For the total system+surroundings, entropy always increases (in any macro-scale process). Your freezing example doesn't rule out that entropy could be a measure of disorder (though I agree that is a somewhat sloppy and oversimplified view). | |

It's a common misconception to say "water freezing represents an increase in order, therefore entropy is violated" meanwhile the increase in order (crystal structure) only arises from an increase in (invariably more) disorder in the thermodynamic system of the freezer. | |

| Oct 20, 2016 at 4:37 | comment | added | Anthony P | You may not be able to understand the concept of entropy in 60 seconds, but I can point out a handful of things you don't know about entropy in 60 seconds or less. That's the point isn't it? At least you'll have somewhere to start! | |
| Oct 20, 2016 at 4:34 | comment | added | Fine Man | I'm not a fan of minutephysics; there's no way someone can understand entropy (or, most topics, for that matter) in 60 seconds. :) | |
