O Levels Chemistry (5070)•5070/12/M/J/21

Explanation
Ambiguous question with multiple incorrect statements
Steps:
- Recall definitions: Freezing (liquid to solid, exothermic), boiling/evaporation (liquid to gas), sublimation (solid to gas), condensation (gas to liquid), melting (solid to liquid, endothermic).
- Check A: Describes freezing correctly—energy released.
- Check B: Boiling at boiling point is not specifically "evaporation" (which occurs below boiling point).
- Check C: Solid to gas is sublimation, not condensation.
- Check D: Melting increases particle energy, not decreases it.
Why A is correct:
- Not applicable—A is actually accurate per thermodynamics (phase change releases heat during freezing).
Why the others are wrong:
- B: Imprecise terminology, but boiling is a rapid evaporation at boiling point—debatably correct.
- C: Wrong name; condensation is gas to liquid by definition.
- D: Wrong energy description; melting absorbs energy per endothermic process.
Not enough information. Final answer: Not enough information.
Topic: Solids, liquids and gases
