Materials' Crystal Properties (1 of 2) (IMAGE) Princeton University Caption 'Ground states' are the lowest energy states of matter. They are created in real life by taking a liquid and slowly cooling it until you reach absolute zero temperature. The resulting arrangement of molecules or particles is a 'ground state,' which often is an ordered crystal structure. This image shows a snapshot of a liquid before the cooling process.
