Cup of Joe - Second Law of Thermodynamics

This is most important of all the laws of thermodynamics….

Of course the crazy way we speak about the Second Law does not help: “In an isolated system, a process can occur only if it increases the total entropy of the system.” Huh? It makes you want to hate Rudolf Clausius. Couldn’t he just say that heat goes from warm to cold?1 Most of us get the heat goes from warm to cold thing. It’s the other simple applications of the Second Law that we miss:

• moisture goes from warm to cold

• moisture goes from more to less

• air goes from a higher pressure to a lower pressure

• gravity acts down
