In a typical phase change diagram, the segments where phase changes occur (like melting, boiling, or condensation) generally represent areas where energy is being absorbed or released.
- Segment BC typically represents a phase change from solid to liquid (melting), which involves the absorption of energy.
- Segment CD typically indicates a phase change from liquid to gas (boiling), which also involves energy absorption.
- Segments AB and DE typically represent temperature changes in a single phase (solid or liquid), where no phase change occurs, and therefore energy is not absorbed in terms of changing states.
Given this information, the correct response would be **BC and CD**, as both segments indicate the absorption of energy during phase changes.
- Segment BC typically represents a phase change from solid to liquid (melting), which involves the absorption of energy.
- Segment CD typically indicates a phase change from liquid to gas (boiling), which also involves energy absorption.
- Segments AB and DE typically represent temperature changes in a single phase (solid or liquid), where no phase change occurs, and therefore energy is not absorbed in terms of changing states.
