Freezing point of energy
WebFeb 11, 2024 · The freezing point is the temperature by which a liquid turns into a solid. When liquid water freezes, energy is subtracted from the system. Any time a substance changes phases, the temperature... In spite of the second law of thermodynamics, crystallization of pure liquids usually begins at a lower temperature than the melting point, due to high activation energy of homogeneous nucleation. The creation of a nucleus implies the formation of an interface at the boundaries of the new phase. Some energy is expended to form this interface, based on the surface energy of each phase. If a hypothetical nucleus is too small, the energy that would be released by forming its v…
