Thermodynamic Properties, Mechanical Properties and Interatomic
Potential in Solids. A Shou-Shi-Ling (手勢令) Game
Abstract
Two formulae were developed to express sublimation enthalpy and Young’s
modulus on a thermodynamic basis. The first formula reveals how the
sublimation enthalpy is correlated with the thermal expansion
coefficient and heat capacity of solids, whereas the second formula
relates the Young’s modulus with sublimation enthalpy and equilibrium
interatomic (intermolecular) distance. These two formulae provide
alternative ways to quantitatively estimate thermodynamic or mechanical
properties of great importance in the development of new materials.
