How is the graph of water's Surface Tension after the Boiling Point?

Question

in my town b.p. is 93.

Answer 1

Presumably you are asking how the surface tension of liquid water varies between the boiling point and the freezing point. The International Association for the Properties of Water and Steam has adopted and recommends the following function for the surface tension:

S(T) = 235.8 * (1-T/647.096)^(1.256) * [1-0.625*(1-T/647.096)]

where T is the absolute temperature (i.e., in kelvins) and S(T) is the surface tension in mN/meter.

See sources.

Answer 2

wouldnt surface tension go down??? I am guessing a linear negative slope.
