Thermal expansion and structure in water and aqueous solutions

Abstract

The thermodynamic equation (∂CP/∂P)T = −T(∂2V/∂T2)P is used as a basis for relating thermal expansion to structure (at several temperatures and pressures) of water and "normal" liquids. Similar considerations lead to a relation between the sign of [Formula: see text] for solutions and classification of solutes as structure-making or structure-breaking.
