Causes of supercooled liquid
At the triple point of a pure substance, the saturated vapor pressure of the liquid is equal to the saturated vapor pressure of the solid. Saturated vapor pressure. Therefore, at this temperature, crystals cannot exist if the tiny crystals are put together with the liquid. Only when the temperature is reduced to a certain temperature at which the saturated vapor pressure of the liquid is equal to the saturated vapor pressure of the tiny crystals, it is possible to remove the Produces tiny crystals. This is why supercooled liquids appear. Supercooled liquid is an unstable metastable state.
