:But you said above ''"Furthermore, it only applies to a closed system, the earth is not a closed system as the sun pours energy onto the earth."'' You're saying that the earth is an '''''open''''' system, that the 2nd Law '''''isn't valid''''' for an open system. If that's the case, then how do you get that coffee to cool down like you described?

:The 2nd Law is happening to this open system on earth; we see it every day. [[User:Karajou|Karajou]] ([[User talk:Karajou|talk]]) 13:25, 18 September 2016 (EDT)

::You are right in that I'm saying the earth is an open sytem and the second law is not valid for an open system.
::The second law talks about entropy. I'm not sure how you are relating it to how the coffee cools down.
::I feel I might be repeating myself, but I'll try to rephrase my point. I feel we are each missing subtleties of each others arguments.
::My point with the coffee example is the if we try apply the law to open systems, we find it easy to come up with a scenario where it does not hold. It is not valid in the same way as neglecting quantum effects when looking at particle physics.
::Please could you expand on what your problem with the coffee is. Thank you [[User:Richardm|Richardm]] ([[User talk:Richardm|talk]]) 13:48, 18 September 2016 (EDT)
