An engineer is conducting an experiment to determine the specific heat capacity of a liquid engine coolant using an electrical immersion heater inside a copper calorimeter. The experimental value obtained for the specific heat capacity is significantly higher than the actual manufacturer specification.
State two distinct improvements the engineer could make to the apparatus or the procedure to obtain a more accurate value.
36 exam-style questions on Edexcel GCSE Physics 14.2 Specific heat capacity and latent heat. Each one has a worked solution and a mark scheme showing where the marks go.
