    Describe briefly how you would carry out a preliminary investigation to find a suitable value to use for this variable?

    My variable is the amount of copper chloride.

    My hypothesis is : "The temperature rise when a metal reacts with a solution of copper chloride varies with the reactivity of the metal".

    Can some one help me and tell me how i should answer this question? xx

    A'ight, so you want to basically find an amount of copper chloride which will give you a large enough temperature rise to help prove your hypothesis yeah?

    What you should do is try relatively small amounts of coopers chloride and relatively large amounts. I would do 3g and measure a temperature rise and then do 15g, then see whichever one provides a feasible increase I.e one that isn't to large or too small x
