Law 2
What is the second law of thermodynamics?

It states that energy systems tend to increase their entropy rather than decrease it. Entropy basicaly means "order" or organization. Gasses have lots of entropy, solids have much less. The flow of entropy moves from solids to gasses. That is basically the second law in a nutshell.
The total entropy of any isolated thermodynamic system tends to increase over time, approaching a maximum value. Entropy is the measure of disorder in a system. In simple terms it means systems slowly become more and more chaotic.

It says that it tends to increase rather than decrease. It is pretyty wierd how it does this. I am guessing this has to deal with the next chapter.
