The second law of thermodynamics says that when energy changes from one form to another form, or matter moves freely, entropy (disorder) in a closed system increases.
The second law of thermodynamics (the entropy law or law of entropy) was formulated in the middle of the last century by clausius and thomson following carnot's. In everyday life we experience many limitations on energy transfers a hot bowl of soup becomes cooler, for example, but a cool bowl of soup never spontaneously heats up.
