What examiners said
Comprehensive responses • A few candidates knew both the arrangement and separation of the particles in the context of gaseous oxygen. Limited responses • A few candidates confused the arrangement and separation of a gas with other states of matter. • Some candidates confused the arrangement of the particles in the gas with the separation of them. • A few candidates thought that this question was...

Comprehensive responses • Most candidates knew the correct change of state for the given description.
— Examiner report, February/March 2026, 0620/32 Q7(c) (Cambridge)
Candidates frequently confused the individual particle behaviour with bulk properties of liquids. Particles of a substance in the liquid state will slide over each other but only in bulk do liquids have a variable shape and fixed volume. Candidates should take care to identify whether they are answering a particle question or general bulk properties of a substance.
