| Apr 20, 2015 at 4:30 | comment | added | pZombie | Correct, but this is not how the 2nd law of thermodynamics is stated in most places, or did i happen to only come across the bad formulations by accident? One would have to calculate the probabilities for all lower entropy states vs the probabilities for all higher entropy states within a closed system combined, from a given entropy state X and only then one could tell if the closed system is more likely to increase or decrease in entropy, unless i am missing something which could very well be. There might be an entropy state X where the likeliness of an increase or decrease are the same. | |
| Apr 20, 2015 at 4:23 | comment | added | Jimmy360 | @pZombie "Entropy is more likely to increase in a closed system which is below a given entropy state X" is a probabilistic statement | |
| Apr 20, 2015 at 4:21 | comment | added | pZombie | There is no probabilistic element contained in "Entropy always increases in a closed system" yet this statement is religiously defended by some. It should be "Entropy is more likely to increase in a closed system which is below a given entropy state X"... Note that this does not necessarily mean that X is the maximum entropy state. Maybe the likeliness of entropy decreasing, rather than increasing inside a close system, is reached BEFORE maximum entropy is reached. In neither entropy state, the statement "entropy always increases" seems correct. | |
