| freezing point |
The temperature at which the first crystal of ice appears during freezing, this can be the same temperature as the melting point, however water and aqueous solutions have a tendency to supercool and ice formation can be delayed to temperatures significantly below the melting point. For example in carefully controlled conditions water may be cooled to -40
