Phase Diagram Of Tempwerature Of Water And Time. Phase amount in the double phase region the lever rule at the point b. These areas all show what you would see if you had a particular mixture of salt and water at a given temperature.
The phase rule calculation for phenol water is shown below. For h2o melting point decreases with increasing pressure for co2 melting point increases with increasing pressure. In thermodynamics the triple point of a substance is the unique combination of temperature and pressure at which solid phase liquid phase and gaseous phase can all coexist in thermodynamic equilibrium.
There would never be any liquid whatever proportions of salt and water you had.
Many of the crystalline forms may remain metastable in much of the low temperature phase space at lower pressures. Ice gain heat in the interval of points a and b and its temperature becomes 0 ºc that is the melting point of it. For example if the temperature was below 211c you would always see a mixture of solid salt and ice. Phase behavior for water is represented on a log pressure versus temperature diagram.
