Problem

Refer to the figure below to answer each question.
The graph depicts heat added in kilojoules per mole, versus temperature, in degrees celsius. The line graph is broken into five sections. Section one represents ice warming, with the graph having a positive slope. It begins at the point (0,-25), and ends at (2,0). Section two represents ice melting to liquid, and has a slope of zero. It begins at (2,0), and ends at (6,0). Section three represents liquid water warming, having a positive slope. It begins at (6,0), and ends at (15,100). Section four represents the liquid water vaporizing to steam, having a slope of zero. It begins at (15,100), and ends at (55,100). Section five represents steam warming, having a positive slope.  It begins at (55,100), and ends at (57,125).

In moving from left to right along the line segment labeled 2 on the graph, heat is absorbed, but the temperature remains constant. Where does the heat go?
