States of matter — IGCSE Science - Combined (0653) questions by topic
Particle behaviour across solids, liquids and gases anchors this topic: explaining why a Bunsen flame changes colour when the air hole opens, comparing gas particle speed and spacing at different temperatures, and identifying shared properties of solids and liquids. Explain, identify and state lead the command words, and explain wants particle movement or spacing described, not just the observed change in state.
This set holds 11 real questions from 2024 to 2025 papers, worth 1 to 11 marks, so single-property recall sits beside particle-model explanations. Submitting each answer for instant marking is useful here, since it checks quickly whether particle speed or spacing, rather than particle number, has been used to explain a temperature difference between two gas samples.
