In this discussion we shall make use of the … WebEntropy is a measure of disorder. The change in entropy is positive, because heat transfers energy into the ice to cause the phase change. This is a significant increase in …
WebThe decrease in chemical potential occurs because there is a lower concentration of water in the solution than in the pure liquid. Statistically, fewer water molecules escape a solution into the vapor phase or freeze out onto the solid phase. That's why salt lowers the chemical potential of water in the solution.

Chemical potentials are important in many aspects of multi-phase equilibrium chemistry, including melting, boiling, evaporation, solubility, osmosis, partition coefficient, liquid-liquid extraction and chromatography. In each case the chemical potential of a given species at equilibrium is the same in all … See more In thermodynamics, the chemical potential of a species is the energy that can be absorbed or released due to a change of the particle number of the given species, e.g. in a chemical reaction or phase transition. … See more Particles tend to move from higher chemical potential to lower chemical potential because this reduces the free energy. In this way, chemical potential is a generalization of "potentials" in physics such as gravitational potential. When a ball rolls down a hill, it … See more Chemical potential was first described by the American engineer, chemist and mathematical physicist Josiah Willard Gibbs. He defined it as follows: If to any homogeneous mass in a state of hydrostatic stress we suppose an infinitesimal … See more Electrons in solids Electrons in solids have a chemical potential, defined the same way as the chemical potential of a chemical species: The change in free … See more The chemical potential μi of species i (atomic, molecular or nuclear) is defined, as all intensive quantities are, by the phenomenological fundamental equation of thermodynamics. … See more The Gibbs–Duhem equation is useful because it relates individual chemical potentials.
