Entropy is a measure of the amount of disorder a system has. More accurately the amount of work that can be extracted from a system. The more entropy a system has the less work that can be done. 1kg of steam at 500 degrees can do lots more work than a kilo of warm water. Entropy always increases in a closed system. Entropy is why everything eventually breaks down.
