Web30 sep. 2016 · Nucleation, the initial process in vapor condensation, crystal nucleation, melting, and boiling, is the localized emergence of a distinct thermodynamic phase at the nanoscale that macroscopically grows in size with the attachment of growth units. These phase changes are the result of atomistic events driven by thermal fluctuations.

Websecondary nucleation is severely a ected by the stirring rate. Primary nucleation usually takes place in the absence of previously formed crystals (though this is not a necessity) when solute molecules meet and form clusters that can grow further to form crystals. This is a stochastic process, and as such, nucleation can be somewhat unpredictable. bring book to baby shower wordingWebThis nucleation process almost never happens in bulk water (homogeneous nucleation), unless the temperatures falls well below the freezing point, to around -30 C.
