Thermodynamic Behavior of Water from Soft-Cell Theory

Abstract

A soft-cell concept is introduced into cell theory to describe the deformable nature of water.  The intermolecular vibration energy of water derived from soft-cell theory is applied to a simple energy model to explore hydrogen-bonding and associated thermodynamic properties.  This study is able to accurately predict the temperature and pressure dependences of hydrogen-bonding in water and explains the distinctive thermodynamic behaviors of water in relation to hydrogen-bonding energy and intermolecular vibration energy.
