Revision as of 11:41, September 25, 2016
, 11:41, September 25, 2016Summarised my proof
I am not denying that entropy can increase in an open system, just that it can easily '''decrease'''. My example above shows an open system in which I have shown using '''mathematics''' that entropy decreases, hence we cannot gerenalise the second law to include open systems as well. Why does that not constitute a proof? [[User:Richardm|Richardm]] ([[User talk:Richardm|talk]]) 12:19, 23 September 2016 (EDT)

Here is my proof that the second law does not apply to open systems. If we say it does, then we are saying "entropy never decreases in an open system"
Let <math>P</math> be the proposition that "entropy never decreases in an open system"
<math>P</math> must be true for '''all''' open systems for the second law to apply to open systems
My example above shows '''mathematically''' an open system in which entropy '''decreases'''
Hence it does not apply to '''all''' open systems.
Hence the second law does not apply to open systems.
If you have a problem with my proof, then please point it out. Otherwise I shall amend the page in a few days.
If you are busy, then I would appreciate it if you say, so that we settle it on the talk page and don't keep changing the article page back and forth. [[User:Richardm|Richardm]] ([[User talk:Richardm|talk]]) 07:41, 25 September 2016 (EDT)
