Introduction

Heating Metals Coursework Plan Aim: I am going to heat up three different metals: 1kg of copper; 1kg of iron and 1kg of aluminum to find compare their rates of heat conductivity. Method: The metals will be cylinders, all of equal mass. They will have 2 holes one for a thermometer (to record the temperature) and another for a 50-Watt electric emersion heater (to heat the metals). I will take a reading every minute for ten minutes. As I only have time to heat each metal for ten minutes, I have decided to heat all the metals to the same temperature before starting the time. This is so that when I plot my graph of the results, I will not have to wait for the densest of the 3 metals to begin to heat up before I get a curve to compare to the results of the other metals. ...read more.

it gets to hot, to prevent this we will ensure that enough time is given for the metal to cool down after the experiment before the metal is touched. The second danger is of electrocution, we will make sure before the experiment begins that all the electrical equipment is in good and working order and is safe. Prediction: I predict the higher the density of the metal the longer it will take to heat up and the lower the density the quicker it will heat up. I think this because the denser a metal the more atoms it has so therefore there is more atoms to heat up meaning a denser metal is slower to gain heat than a less dense metal because it has more atoms. The densest of the metals is copper; followed by iron then the least dense is aluminium. ...read more.

Conclusion

This shows again that aluminium is a better conductor than iron and copper both of which have a higher density. The results support my conclusion because I predicted that the lower the density the quicker it would take to heat up and the higher the density the slower it would take, as I have said this is what we got from our results. Evaluation My method was effective because it gave us very accurate results, was relatively safe and was very easy to carry out. We got no anomalous results which also shows it was a very effective method. To improve our experiment we could have recorded for longer amount of time, we could have used a digital thermometer this would have made our results perfectly correct. Future work could involve using other types of metals, using different weights of metals or using an electric emersion heater of a higher wattage. ...read more.

    This means that as the group is descended the outer electrons are more distant from the nucleus, there will be more shielded from the effects of the nucleus by inner shells and so progressively the outer electrons become less attracted to the nucleus.

    However in this investigation there may be a point where the temperature will rise no further. This would be because if the amount of iron added is greater than the amount of copper in the solution there will not be enough copper to react with the iron.

    Distribution: iv. The distribution aspect is one of the important requirements of mass customization. After passing through the flexible production process each individual product must reach to the right person. Also, as the production stages may be in different places, the passage of the semi-finished products within the process should be fool proof.
