### Entropy and The Second Law CourseNotes Just Now The second law also predicts the end of the universe: it implies that the universe will end in a "heat death" in which everything is at the same temperature. This is the ultimate level of disorder; if everything is at the same temperature, no work can be done, and all the energy will end up as the random motion of atoms and molecules. Entropy.

### Statistical Interpretation of Entropy and the Second Law 7 hours ago

1. What are the possible outcomes of tossing 5 coins? Each coin can land either heads or tails. On the large scale, we are concerned only with the total heads and tails and not with the order in which heads and tails appear. The following possibilities exist: 5heads,0tails4heads,1tail3heads,2tails2heads,3tails1head,4tails0head,5tails5heads,0tails4heads,1tail3heads,2tails2heads,3tails1head,4tails0head,5tails These are what we call macrostates. A macrostateis an overall property of a system. It does not specify the details of the system, such as the order in which heads and tails occur or which coins are heads or tails. Using this nomenclature, a system of 5 coins has the 6 possible macrostates just listed. Some macrostates are more likely to occur than others. For instance, there is only one way to get 5 heads, but there are several ways to get 3 heads and 2 tails, making the latter macrostate more probable. Table 1 lists of all the ways in which 5 coins can be tossed, taking into accou...

1. Waste energy is associated with all processes. This waste can be reduced, but it can never be eliminated. Anyone who says otherwise is trying to con you. The Second Law of Thermodynamicsis a statement of the painfully obvious; that is, at least it's obvious to us now. The statements you are about to read were worked out over a period of many years, were refined and clarified by countless minds, and were gradually combined into one large idea that we now recognize as a comment on the fundamental behavior of the universe. Of all the relationships in physics given the title of "law", the Second Law of Thermodynamics is the one for which there appears to be no exception. Anyone who disagrees with it or says they have a method to avoid it is immediately and rightfully dismissed as a naif who doesn't understand the law, a crackpot pushing an agenda, or the perpetrator of some kind of hoax. When someone says they've found a way around the Second Law of Thermodynamics, chances are quite goo...
