Scientists also study thermodynamic data such as Henry's law coefficients.
All thermodynamic data is a non-linear function of temperature (and pressure), but there is no universal equation format for expressing the various functions.
The table format is a common way to display thermodynamic data.
The table below gives thermodynamic data of liquid CO in equilibrium with its vapor at various temperatures.
Explanations of acid "strengths" in terms of "resonance" or "inductive" effects are bogus and not supported by the thermodynamic data, where available.
Examination of the thermodynamic data shows that both enthalpy and entropy effects determine the result.
The Dortmund Data Bank is a factual data bank for thermodynamic and thermophysical data.
Although a body of thermodynamic data is available in the literature that provides the basis for such a description, physical insight is still lacking.
You might try consulting tables of thermodynamic data of the elements, which might give the density as a function of temperature.
These works are among several reference books for thermodynamic data.
