    Im doing the controlled assessment section 2 and im stuck on this question

    "most investigation contain errors suggest the source of significant errors, suggest a change to reduce this error and explain how the change would make the results more accurate?"

    Hypothesis: The temperature rise when a metal reacts with a solution of Copper Chloride varies with the reactivity of the metal.

    Please Answer as i have my exam on monday ^.^

    the source of significant errors would be the therometer because they are hard to read and not that acurrate to make my resluts more acurrate i would use a digital therometer because they are easier to read and reduce human error
