dag Sofie,
ik ben bang dat we je moeten telurstellen:
https://en.wikipedia.org/wiki/Leidenfrost_effectThe temperature at which the Leidenfrost effect appears is difficult to predict. Even if the volume of the drop of liquid stays the same, the Leidenfrost point may be quite different, with a complicated dependence on the properties of the surface, as well as any impurities in the liquid. Some research has been conducted into a theoretical model of the system, but it is quite complicated.[1]
De Engelse wikipedia vertelt nog veel meer. Inclusief een berg wiskunde, maar niks om een temperatuur mee te berekenen.
Groet, Jan
