His name describes a relation between the polarizability of a molecule and the dialectric constant of a gas when it is paired with Mossotti.  The developer of the virial equation, his name also describes an equation that explains the fact that the relationship between the temperature of a liquid and its vapor pressure is not a straight line when paired with Clapeyron.  The creator of the concept of entropy, FTP, identify this German scientist who, independently of Lord Kelvin, arrived at the second law of thermodynamics.
