What examiners said
Many candidates correctly identified the part of the graph where melting was occurring.
— Examiner report, May/June 2025, 0973/41 Q5(c)(i) (Cambridge)
The idea that melting of a pure substance occurs at one temperature only was well understood. Being able to explain this in terms of the horizontal part of the graph was less well expressed.
— Examiner report, May/June 2025, 0973/41 Q5(c)(ii) (Cambridge)
The changes of state were almost always correctly identified.
