Water-ice transitions - Big Chemical Encyclopedia

Paul Ehrenfest classified phase transitions based on the behavior of the thermodynamic free energy as a function of other thermodynamic variables. Under this scheme, phase transitions were labeled by the lowest derivative of the free energy that is discontinuous at the transition. First-order phase transitions exhibit a discontinuity in the first derivative of the free energy with respect to some thermodynamic variable. The various solid/liquid/gas transitions are classified as first-o… WebbDirector of Engineering: 12/2024-9/2024 Senior Energy Engineer: 05/2016-12/2024 Director of Engineering at Phase Change Energy Solutions … Webb18 dec. 1998 · This transition plays a key role in the geophysics, biology, and remote sensing of sea ice.
