Hello, I am looking for a general formula for the surface tension dependence with respect to temperature. I am aware of the Eötvös rule (http://en.wikipedia.org/wiki/Eötvös_rule), but I only found data for water, and wonder if there are some for other compounds. Also, I wonder if speaking of surface tension for water with a temperature below the freezing point is meaningfull ? To my opinion, as soon as a liquid freezes, it takes a cristal form with much stronger links molecules between themselves, so that the Kelvin effect would no more take place. Am I right ?
