The paper also evaluates experimental skills through measuring water’s specific heat capacity, addressing hazards, methods, and sources of error, plus percentage difference calculations from experimental and actual values. Electrical investigations include current-voltage behavior in LEDs and resistance calculations using the equations sheet.","Please write clearly in block capitals.Centre numberCandidate
