Read each question carefully and provide your best answer. Refer to the heating curve diagram provided for relevant questions.
Observe the heating curve below for a substance.
1. What does the flat segment(s) on a heating curve represent?
Increase in kinetic energy
Phase change
Decrease in potential energy
Temperature increase
2. During which segment(s) is the substance entirely in the liquid phase?
Segment A
Segment B
Segment C
Segment D
3. The temperature at which a solid turns into a liquid is called the .
4. During a phase change, the added heat energy is used to overcome forces between particles, rather than increasing their kinetic energy.
5. A heating curve shows the change in temperature of a substance as heat is continuously added over time.
True
False
6. The boiling point of a substance can be identified as the first plateau on its heating curve.
True
False
7. Explain the difference between sensible heat and latent heat in the context of a heating curve.
8. Describe what is happening to the particles of the substance during the segment where it is boiling.
