::::::::: I don't have any reason to doubt your formulas for entropy, and thanks for posting them. But for the purposes of the Second Law the dictionary definition for entropy works fine: a measure of disorder in a system. It's always increasing unless there is some kind of intelligent intervention, like [[God]] creating the world. Perhaps [[faith]] can operate to reduce entropy. Otherwise, without intervention or faith, disorder is always increasing, and the Second Law is an expressing of that logical truth. Otherwise a [[perpetual motion machine]] would be possible, and it is isn't.

:::::::::: Considering we're talking about physics the definition used by physicists should take precedent. But fine, often "a measure of disorder in a system" is used to define entropy for the layman. However, under this definition the entropy ''still'' increases when ice melt since the structure becomes less ordered. --[[User:MatthewQ|MatthewQ]] 23:15, 13 June 2012 (EDT)
