Solution: Heating curve for water. Changes that occur when 1.00 mol of H2O is heated from H2O(s) at -25 to H2O(g) at 125 at a constant pressure of 1 atm. Even though heat is being added continuou

Problem

A graph has heat added on the x-axis (unscaled, increasing) and temperature in degrees C on the y-axis, ranging from negative 25 to 125 with intervals of 25. The line plotted is divided into lines AB, BC, CD, DE, and EF as water goes through phase changes as heat is added, changing from solid ice, to liquid water, to steam. Line segment AB goes from negative 25 to zero degrees and the phase is cce (solid). Line segment BC is at zero degrees but correlates to Phase change: Horizontal line.  Melting, temperature does not change until all H2O (solid) becomes H2O (liquid). Line segment CD extends from o to 100 degrees and the phase is water (liquid). Line segment DE is at 100 degrees and Phase change: Horizontal line. Vaporization, temperature does not change until all H2O (liquid ) becomes H2O (gas). Line segment EF extends from 100 to 125 degrees and the phase is steam (gas).


Heating curve for water. Changes that occur when 1.00 mol of H2O is heated from H2O(s) at -25 to H2O(g) at 125 at a constant pressure of 1 atm. Even though heat is being added continuously, the system temperature does not change during the two phase changes (red lines).

What process is occurring between points C and D?
