What examiners said
Candidates often stated that either the temperature or volume had increased rather than talking about the effect on pressure. Other candidates described the effect on the particles rather than the effect on pressure. Candidates need to answer the specific question asked, in this case the effect on pressure.
— Examiner report, May/June 2025, 0973/31 Q5(c) (Cambridge)
The increase in pressure caused by increase in temperature was usually explained by the increased speed of particles and their increased rate of collision with the tyre walls. Collision between particles was not accepted.
— Examiner report, May/June 2019, 0973/41 Q12(b) (Cambridge)
The majority of candidates could describe molecules colliding with the walls of the tyre. Fewer describe this as exerting a force with most referring to exerting a pressure, which was already given in the question.
