Solution: Two heating curves, A  and B , are shown. In both cases, point 1 corresponds to the crystalline solid phase.In graph A, what process does the 3-4 line segment correspond to?

Problem

Two heating curves, A Line graph A shows temperature versus heat added, with the line plotted in each divided into numbered segments. Temperature and heat increase linearly from points 1 to 2, heat increases while temperature remains constant from points 2 to 3, temperature and heat increase linearly from points 3 to 4, heat increases while temperature remains constant from points 4 to 5, and temperature and heat increase linearly from points 5 to 6. The slope of the line for points 3 to 4 is steeper than that of the segment from 1 to 2, while that of the segment for 5 to 6 is even steeper. and B Line graph B shows temperature versus heat added, with the line plotted in each divided into numbered segments. Temperature and heat increase linearly from points 1 to 2, heat increases while temperature remains constant from points 2 to 3, temperature and heat increase linearly from points 3 to 4, heat increases while temperature remains constant from points 4 to 5, temperature and heat increase linearly from points 5 to 6, heat increases while temperature remins constant from point 6 to 7, and temperature and heat increse linearly from points 7 to 8. The slope of the line for points 1 to 2 and 7 to 8 are the steepest, while the slope of the line for points 5 to 6 is the least steep., are shown. In both cases, point 1 corresponds to the crystalline solid phase.

In graph A, what process does the 3-4 line segment correspond to?
