Variables Used

Surface Entropy - (Measured in Joule per Kelvin) - Surface Entropy is defined as the derivative of surface tension with respect to temperature.
Empirical Factor - Empirical Factor is the value originating in or based on the empirical observation that relates the surface tension to the critical temperature.
Constant for each Liquid - Constant for each Liquid is the constant being the surface tension of a liquid at absolute zero.
Temperature - (Measured in Kelvin) - Temperature is the degree or intensity of heat present in a substance or object.
Critical Temperature - (Measured in Kelvin) - Critical Temperature is the highest temperature at which the substance can exist as a liquid. At this phase boundaries vanish, and the substance can exist both as a liquid and vapor.

STEP 1: Convert Input(s) to Base Unit

Empirical Factor: 1.23 --> No Conversion Required

What is the Eötvös Rule?

The Eötvös rule, named after the Hungarian physicist Loránd (Roland) Eötvös (1848–1919) enables the prediction of the surface tension of an arbitrary liquid pure substance at all temperatures. The density, molar mass, and the critical temperature of the liquid have to be known. At the critical point the surface tension is zero.
