Entropy in real life

Postby juchung7 » Sun Feb 04, 2018 11:41 pm

This is kind of random, but I was just wondering, how does entropy increase through air conditioning? Or any kind of cold-increasing system?

The entropy of a room may decrease with the cooling of the system. However, that does not mean that the whole system would have the entropy decrease. The heat particles just flow to a different object. DeltaS means the change in total entropy as the energy of contents of the two components change so the two components (I am assuming the room being air conditioned and its surroundings) would just have a change in entropy where the room's entropy would be decreasing.
