What characteristics are shared by both heating AND cooling curves?
KE increases steadily.
Phase changes happen when the temperature increases.
Phase changes happen when the temperature stays the same.
Temperature is plotted on the Y-axis.
Added heat is plotted on the X-axis.
Changes in PE result in a phase change.
Line segments that are at an angle (slanted) represent a substance in a single
phase of matter.
Line segments that are horizontal (flat) represent a substance in a single phase of
matter.
