Summary of state changes.
Just like heating curves cooling curves have horizontal flat parts where the state changes from gas to liquid or from liquid to solid.
A heating or cooling curve is a simple line graph that shows the phase changes a given substance undergoes with increasing or decreasing temperature.
The ice could then be cooled to some point below 0 c.
Heycock and neville 1890 1897 took liquid alloys and cooled them through the liquidus and measured the temperature using simple thermocouples the time at each temperature measurement was also.
Making such measurements over a wide range of pressures yields data that may be presented graphically as a phase diagram.
