Introduction For our experiments‚ I was investigating what affects the rate of reaction. We used Hydrogen peroxide to test the rate of reaction‚ with the temperature of this being our variable that we changed. Hydrogen peroxide is a clear‚ colourless liquid which has various amounts of uses within the laboratory‚ industrial purposes and even in our households. It is mainly used for cleaning products and hair dye but is also used for paper making. Hydrogen peroxide is made up of two oxygen atoms and two hydrogen

An investigation into the specific heat capacity of a solid Introduction: In this experiment I investigated the specific heat capacity of brass and aluminium‚ in order to do this I arranged a series circuit with a heater‚ the heater would go inside the brass and aluminium and heat it for an amount of time in which I decided‚ I also used the voltmeter in parallel. This arrangement made me able to arrange the equation VIT= mcΔθ‚ since the electrical energy in would be equal to the mass times the
