Subject field(s)
  • Chemistry
  • Thermodynamics
  • Glaciology
  • Fluid Mechanics and Hydraulics (Physics)
DEF

The temperature at which a liquid solidifies under the influence of a particular set of conditions.

OBS

It may or may not be the same as the melting point or the more rigidly defined true freezing point or (for water) ice point. It is not an "equilibrium" property of a substance; it applies to the liquid phase only. The freezing point is somewhat dependent upon: the "purity" of the liquid; the volume and shape of the liquid mass; the availability of freezing nuclei; and the pressure acting upon the liquid.

CONT

Construir un diagrama eutéctico simple en un equilibrio sólido-liquido. Efectuar el análisis térmico de las curvas de enfriamiento y los sistemas eutécticos simples. Construir los diagramas de temperatura de congelación en formación de compuesto. Graficar diagramas de soluciones sólidas y determinar su elevación de su temperatura de solidificación.

OBS

Esta información es importante porque un material congelado puede reventar el recipiente donde está contenido o los peligros pueden cambiar.
