| Description |
Deutsch: 20 Gramm Glaubersalz (Decahydrat, aus der Apotheke) wurden in 100 Milliliter Wasser gegeben. Beide Stoffe und auch der Messbecher hatten vorher dieselbe Temperatur, nämlich 17 °C. Direkt nach Zugabe der Chemikalie fiel die Temperatur der Lösung sturzartig auf nur noch 11 °C ab. An dem Moment entstand die Aufnahme hier. Die Temperatur wurde hier mit einem Petroleumthermometer gemessen. Das Glas fühlte sich sehr deutlich spürbar fast eiskalt an. Das Bild entstand in der Mathe-AC Lernwerkstatt in Aachen.
