This diagram covers Heating Curve for Water within States of Matter for GCSE Physics. Revise States of Matter in Particle Model for GCSE Physics with 13 exam-style questions and 30 flashcards. This topic appears less often, but it can still be a useful differentiator on mixed-topic papers. It is section 5 of 13 in this topic. Focus on the labels, the relationships between parts, and the explanation that turns the diagram into an exam-ready answer.
📊 Heating Curve for Water
KEY INSIGHT: FLAT sections = state change (energy breaks/forms bonds, temperature constant). SLOPED sections = heating within same state (energy increases particle speed, temperature rises).
Practice questions for States of Matter
In which state of matter are particles arranged in a regular pattern and only vibrate about fixed positions?
Explain what happens to the particles in a solid when it is heated until it melts. Include what happens to the temperature during melting.
