This Demonstration shows a temperature-entropy () diagram for water. Use the checkboxes to add or remove a property from the diagram. You can show lines of constant enthalpy (green), pressure (blue) and quality (mass% vapor, purple). Check "phase envelope" to view the saturated liquid (magenta) and saturated vapor (orange) curves and the location of the critical point. Check "grid lines" to display grid lines.
