What examiners said
This question was very well answered by most candidates who gained at least partial credit. Most candidates referred to evaporation happening only on the surface or there being no bubbles present in evaporation. These were alternative ways of expressing the same idea. Weaker candidates gave these as two differences and omitted to state that evaporation does not take place at a specific temperature...
— Examiner report, May/June 2024, 0625/42 Q4(a) (Cambridge)
Candidates who followed the guidance in the question were able to write concisely and addressed all the necessary points. Some candidates copied the list of apparatus and other information given in the question. This was unnecessary and often introduced a vague explanation of the investigation. A concise explanation of the method was required. Candidates needed to concentrate on the readings to b...
— Examiner report, October/November 2023, 0625/61 Q4 (Cambridge)
Many candidates chose the correct option. However, other candidates confused boiling and evaporation and incorrectly chose option D.
