D

Examiners report

This question gives good discrimination although slightly more candidates chose option A instead of the correct option D. It is unusual that the correct response is 'cannot be determined' but the lack of mass or specific heat capacity in the data should have alerted candidates that they were not able to work out or compare how much thermal energy was supplied.
