H2o and d2o density
WebThe unusual volumetric properties of both proteated and deuterated water are explored by carefully comparing their volumetric properties and developing a heuristic molecular model to describe the behavior. The behavior is further explored by relating these properties to other well-known thermodynamic properties.
