On a Statistical Interrelation Between Boiling Point and Debye Temperature

Debye temperature Θ D of a substance plays a role in Solid State Theory; its experimental determination however requires a sophisticated device such that the value of Θ D is not available for many substances. A statistical possibility of approximation of Θ D is presented for substances whose boiling point and molecular mass are known. This approximation is based on the notion of zero entropy temperature, which serves as a regressor; statistical considerations reveal a strong correlation between the regressor and Debye temperature. This result can be interpreted as a bridge between Fluid and Solid State Theories.
