![]() This is often taken to mean that "disorder always increases" and is frequently misinterpreted. The second law of thermodynamics states that "the entropy of an isolated system does not decrease". “ ”Nothing in life is certain except death, taxes, and the second law of thermodynamics. ![]() When this is brought up, apologists usually either get angry, or start dodging the question by trying to explain how God is beyond the laws of physics. The first law also renders any creation event impossible, because it is, by definition, creating something from nothing.The big bang theory doesn't necessarily mean the universe came from nothing.They choose to ignore two key facts, however: This law is often brought up by apologists when trying to disprove the big bang theory, usually in the argument from first cause form. And as with all the other laws of thermodynamics, it only applies to a closed system. To put it simply, you can't create energy or matter, just change its arrangement. It is an expression of the law of conservation of energy energy cannot be created or destroyed, only change form, as with matter becoming energy or vice versa. ![]() The first law of thermodynamics is that you do not talk about thermodynamics states that the total energy of the universe is constant. In fact, it's arguably not really a "law" at all, but more just a definition of what is meant by "temperature". The need to formulate it as a formal law arose after the other laws had been established, so it was named the zeroth law in a backronym-ish manner. The zeroth law is kind of a no-brainer, and was obviously known before the first, second, and third laws of thermodynamics were described. If this was possible, periodically connecting the systems A and C through a heat engine would create a perpetual motion machine. It's not possible to have three systems, A, B, and C, where A is in equilibrium with B and B in equilibrium with C, but A is not in equilibrium with C. The zeroth law of thermodynamics states that "if two systems are in thermal equilibrium with a reservoir, then they are in thermal equilibrium with each other." It means that thermal equilibrium is a transitive relation.
