The second law of thermodynamics states that: 🙋The disorder of a system is always increasing. Entropy is the measure of that disorder. But why measure disorder, and is it even possible? Physically, we can't measure entropy, but we can calculate it. It's one of the main determinants of...
all of its ligands.” The basic premise of GA scheme is that one can subdivide an arbitrary chemical compound into a set of smaller structural units in such a way that the overall thermodynamics of that compound can be calculated from thermodynamics associated with the smaller structural units. ...

The performance and thermal properties of convective–radiative rectangular and moving exponential porous fins with variable thermal conductivity together with internal heat generation are investigated. The second law of thermodynamics is used to investigate entropy generation in the proposed fins. The model...

1.3.5 The second law of thermodynamics (SLT) Although a spontaneous process can proceed only in a definite direction, the FLT gives no information about direction; it merely states that when one form of energy is converted to another, the quantities of energy involved are conserved regardless of...
We have highlighted in the previous sections the influence of thermodynamics in the early stages of the development of information theory. However, information entropy is of enormous importance in other areas of physics as well. 8.1. Thermodynamic Entropy The thermodynamic entropy for an ideal gas is...
Since it is known that the choice of a graph matrix does affect the evolution of quantum walk11,12, we claim that there is a need to design the entropy formula which accepts each of the above-mentioned matrices. Entropy in the work4 is defined as the von Neumann entropy of Gibbs state...
As might be expected, substances with very complex formulae give high values, the increase with molecular complexity being very distinct. Conformational contribution in fusion entropy values for flexible molecules is about 7–12 J/K/mol. Although translational ΔfusStrn and rotational contributions Δ...
