Eotvos Ramsay-Shield relation of Surface Tension and Temperature Calculator
M=Molecular Weight; d= density; γ= Surface Tension ; k=Eotvos-Ramsay Coefficient ; tc= Critical Temperature ; t= System Temperature
This online chemistry calculator is based on the Eötvös rule. Eötvös rule relates the surface tension and temperature linearly. The coefficient k (Eotvos-Ramsay Coefficient) normally has a value of 2.1×10−7 J/K.mol2/3. However in liquids having associated state of molecules will have lower k value. For example, since water, alcohol, carboxylic acid etc have inter-molecular hydrogen bonding, they show a lower value of k.
