The flow of energy (by heat exchange) to places with lower concentrations is called the 'heat flow.'

Not cleaning up would always result in an increase of entropy in your room! Remember how easy it was to let the room turn into a uniform mess (disorder) and remember how hard it was to clean it up until it fit a specific, non-uniform design (order). Imagine your old room at your parent's house. In this context 'increasing disorder' means the decline in organization that occurs without intelligent intervention.

2 Second Law compared with other physical laws.

In the terminology of physics, the Second Law states that the entropy of an isolated or closed system never decreases. The Second Law of Thermodynamics disproves the atheistic Theory of Evolution and Theory of Relativity, both of which deny a fundamental uncertainty to the physical world that leads to increasing disorder. This law also predicts the tendency for cables, cords, and wires, to self-entangle and repeatedly require straightening. This law makes it impossible to build a perpetual motion machine - the increase in entropy inevitably derails the system even if energy remains constant. As explained in the Hebrews 1:10, the universe shall 'wear out' like a 'garment', i.e., entropy is always increasing. The Second Law of Thermodynamics is the result of the intrinsic uncertainty in nature, manifest in quantum mechanics, which is overcome only by intelligent intervention. Isaac Asimov, Smithsonian Institute Journal, June 1970, p. In fact, all we have to do is nothing, and everything deteriorates, collapses, breaks down, wears out, all by itself - and that is what the second law is all about. How difficult to maintain houses, and machinery, and our bodies in perfect working order: how easy to let them deteriorate. Even if we never enter it, it becomes dusty and musty. We have to work to straighten a room, but left to itself it becomes a mess again very quickly and very easily. Viewed that way, we can see the second law all about us. As the self-described atheist scientist Isaac Asimov admitted:Р”Р„nother way of stating the second law then is: The universe is constantly getting more disorderly. This principle correctly predicts that heat will never flow from a cold body to a warmer one, unless forced to do so by a man-made machine. The Second Law of Thermodynamics is a fundamental truth about the tendency towards disorder in the absence of intelligent intervention.
