But, no one has ever observed spontaneous transfer of heat from a colder body to a hotter body.Įven though such phenomenon are permissible by the first law, such processes never occur naturally. Heat always flows from a hotter body to a colder one spontaneously. Natural systems always have a tendency to maximise their entropy.Īnd that's what the second law is all about.Ĭonsider for example, the transfer of heat from one body to another in contact due to the temperature difference. In other words, second law specifies the direction of evolution of a natural process. Atomic fusion, being specific, can be considered a matter of the design of the elements involved.All irreversible (natural and spontaneous) processes are characterized by the fact that entropy always increases in such processes.Īnd the second law of thermodynamics logically means that entropy always tends to increase.Ī physical system shall always proceed to a state of maximum entropy. It should be noted as well that the reactions are specific, and take place in exactly the same way with the same elements under the same conditions. Regarding thermonuclear fusion, any increase in complexity or order of the new elements is at the expense of a tremendous loss of heat and light which then diffuse, as per the Second Law of Thermodynamics. I don’t see how one can divorce the implications from the law.” And entropy changes imply changes in randomness, which implies an inherent direction that a process will take (without outside intervention). Yes, I know that the physicists insist that the 2LOT is ‘only about heat transfer,’ but in chemical contexts, it is acceptable to express it in terms of entropy. The comment is as follows: “In addition to crystallization and biological growth, the other example that consistently comes up (at least with high schoolers) when discussing entropy is thermonuclear fusion.” I submitted the above response to a high school teacher of physics and chemistry and asked for comment. For some, it is a belief, perhaps, but it cannot be rightly called either fact or theory when it refers to the “bacteria to bears” progression. Theories are testable and, ideally, falsifiable. Perhaps it should also be mentioned that evolution as inferred from the fossil record is not even a theory. As in the case of crystallization, the execution of the biological design requires specific environmental requirements or it cannot proceed. It is, again, not a random ordering from a non-ordered condition. The DNA is there from the beginning, along with whatever might be “sparking” it, and the rest is simply a matter of following instructions. However, the design is already present in these beginnings of life. Heat is diffused.īiological increase in complexity is exemplified by a seed becoming a bush or flower or tree, or a fertilized egg becoming a person. What is interesting, however, about this particular thing, is that there is a heat transfer involved in crystallization and the Second Law of Thermodynamics is not violated therein. It is not a random ordering of a material from a non-ordered state, but rather the result of a specific design involved in the material and can be counted on to happen every time under the prescribed conditions. It is a phenomenon that is intrinsic to the atomic structure of the element or compound being considered. Crystallization, however, happens to specific elements at specific times under specific conditions. The first is in regard to chemical changes that go from simple to complex, and the second to biological changes that go from simple to complex.Īn example of the first is a snowflake - or any crystallization. I have seen two responses from evolutionists regarding this tendency toward entropy in the universe (aside from “You’re kidding!”). The tendency from order to disorder, from complexity to simplicity, from life to death, is something we all see and can both define and measure. It is perhaps safer to refer to a more generalized tendency toward entropy which is far more inclusive of other phenomena. Response: The Second Law of Thermodynamics has to do with heat transfer explicitly. Question: I haven’t had a chance to read what you’ve written yet, but I’d just like to say that the THEORY of evolution goes against the Second Law of Thermodynamics (out of order, chaos will be created).
