9 Thermodynamics and Entropy

One topic that is relevant to this discussion is Thermodynamics and its subset entropy.
Thermodynamics is the study within physics that seeks to understand the relationship between heat and mechanical energy. Physicists have observed several laws, which aid the engineering field. Knowledge of these laws enables one to design an engineering system or machinery that will work as intended.
The first law of thermodynamics is an expression of the principle of conservation of energy. It says that energy can be transformed, i.e. changed from one form to another, but cannot be created or destroyed. Therefore all energy was created in the past.
Second Law of Thermodynamics says that heat cannot be transferred from a colder to a hotter body. The available energy to do work continually decreases. Entropy is the measure of the disorder or randomness of energy and matter in a system. This law also states that the entropy of an isolated system always increases with time. Because of the second law of thermodynamics both energy and matter in the Universe are becoming less useful as time goes on. Perfect order in the Universe occurred the instant after the creation when energy and matter and all of the forces of the Universe were unified. Order began to decline with the Fall. Or to put it another way entropy increased. The Universe appears to run “downhill” to an eventual heat death when no temperature differences will exist because no energy is available and this will result in uniform disorder or chaos.
