82Atmospheric reentry — refers to the movement of human made or natural objects as they enter the atmosphere of a planet from outer space, in the case of Earth from an altitude above the edge of space. This article primarily addresses the process of controlled reentry… …
83Solubility — Soluble redirects here. For the algebraic object called a soluble group , see Solvable group. Solubility is the property of a solid, liquid, or gaseous chemical substance called solute to dissolve in a solid, liquid, or gaseous solvent to form a… …
84STO-nG basis sets — STO nG basis sets are the minimal basis sets, where n represents the number of primitive Gaussian functions comprising a single basis set. For minimal basis sets, the core and valence orbitals are represented by same number primitive Gaussian fu …
85Ising model — The Ising model, named after the physicist Ernst Ising, is a mathematical model in statistical mechanics. It has since been used to model diverse phenomena in which bits of information, interacting in pairs, produce collectiveeffects.Definition… …
86Arrhenius equation — The Arrhenius equation is a simple, but remarkably accurate, formula for the temperature dependence of the rate constant, and therefore, rate of a chemical reaction. [http://www.iupac.org/goldbook/A00446.pdf Arrhenius equation] IUPAC Goldbook… …
87Dimensionless quantity — In dimensional analysis, a dimensionless quantity or quantity of dimension one is a quantity without an associated physical dimension. It is thus a pure number, and as such always has a dimension of 1.[1] Dimensionless quantities are widely used… …
88Internal energy — In thermodynamics, the internal energy of a thermodynamic system, or a body with well defined boundaries, denoted by U , or sometimes E , is the total of the kinetic energy due to the motion of molecules (translational, rotational, vibrational)… …
89Chemical kinetics — Reaction rate tends to increase with concentration a phenomenon explained by collision theory. Chemical kinetics, also known as reaction kinetics, is the study of rates of chemical processes. Chemical kinetics includes investigations of how… …
90Semi-empirical mass formula — In nuclear physics, the semi empirical mass formula (SEMF), sometimes also called Weizsäcker s formula, is a formula used to approximate the mass and various other properties of an atomic nucleus. As the name suggests, it is partially based on… …
