A student determines the specific heat capacity of an iron block using an electrical heater. The value obtained from the experiment is higher than the accepted textbook value of 450 J/kgdegC.
State two ways the student could improve the overall experimental setup or procedure to obtain a more accurate value.
36 exam-style questions on Edexcel GCSE Physics 14.2 Specific heat capacity and latent heat, covering 14.2.1 Heating, temperature and changes of state, 14.2.2 Specific heat capacity and specific latent heat, 14.2.3 Specific heat capacity calculation, 14.2.4 Specific latent heat calculation, and 14.2.5 Reducing energy transfer through thermal insulation. Each one has a worked solution and a mark scheme showing where the marks go.
