Increase of entropy examples
WebAug 28, 2024 · We estimate entropy change as Δ S = Q / T av , where T av is 23 ° C ( 296 ° K ) for the hot water. The average temperature for the cold water is 21 ° C ( 294 ° K ) . The change in entropy of ... WebEntropy is the measure of the disorder or randomness in a system. In other words, if you drop a box of matches on the floor, the matches will fall all over the place, which is an increase in entropy. For an example of decreased entropy, if you build a house you are making order, not chaos, so the entropy-the disorder of a system-is decreased.
