Introduction
Many students mix up boiling and evaporation — and that can cost marks! This PSLE Science boiling question tests a basic but important concept: what boiling actually means. Understanding this helps students answer confidently in exams.
The Question
Students are asked to state what boiling means.
This looks simple, but PSLE markers expect a precise scientific definition.
Step-by-Step Explanation
✔ Boiling occurs at a fixed temperature (boiling point).
✔ It happens throughout the liquid, not just the surface.
✔ The liquid changes state into gas.
✅ Correct definition:
A liquid becomes a gas at its boiling point.
This is the expected PSLE answer.
Key Concepts
Boiling
- Liquid → gas
- Happens at boiling point
- Occurs throughout the liquid
Evaporation (different!)
- Happens at any temperature
- Only at the surface
Students must not confuse these two.
Tips for Students
✔ Memorise the definition
✔ Use correct keywords like “boiling point”
✔ Avoid writing long unnecessary explanations
✔ Practise similar PSLE Science questions
For Parents
This topic builds:
