Introduction

Copper Research * Some possible uses for copper are for money, roofing sheets, roofing tiles, flashing strips, gutters, downspouts, cupolas, vents, hand rails, light fixtures and signs are available in copper. In order to get a profit I would try to sell my copper to a good company. * I would try to sell my copper for as much I can sell in order to make a profit. It might get us more experience because if we do business with the right people we make a profit and get experience. * Ore malachite is like a green mineral. This is a carbonate like Azurite. Researching Copper Electrics and Electronics In practical terms, copper is indispensable, not only in a multiplicity of functions in the world around us, but to our basic health, as it is a vital trace element in our daily diet, helping to ensure the health of body and brain. ...read more.

Conclusion

0.08 labour 10.00 per hour 3 people for 2 hours �60 Evaluation The experiment went wrong because we separated it the wrong way. The way we can change and make it better we can get a more precise heating then use them as much more. Also the experiment went wrong because the calculations fo the temperature didn't turn as planned. We could have tried to improve it by making the temperature and using a more careful way to separate the metals. We used the equipment in the wrong way we should have been more careful and try to do the experiment the right way in order to get better results.

    I choose Miss Claudia Zacarian but she already had her 5 students, but after talking to Pat O'Malley they allowed me to be with her. We started working and giving a little bit of shape to the project, I plan the whole essay with her.

  2. Technology Evaluation

    If there was enough equipment it would have been a lot easier and quicker for the train to be made. I would have used different materials, I would have used oak wood instead of chipboard because oak wood makes

  1. EFFECT OF MOISTURE ON THE MECHANICAL PROPERTIES OF NYLON

    Hydrolytic degradation is a chemical reaction, which occurs at high temperature with some polymers in the presence of water. It causes primary bonds in the molecular chains to be severed thus reducing molecular weight. Over drying (i.e. <0.08% water) will remove the plasticizing effect of the water molecules and make the resin very viscous and hard to flow.

  2. Critically discuss the importance of materiality for theories of practical reasoning.

    so it follows that the very idea of human agency - contra the autonomous figure portrayed in the pre-social state of nature - is already deeply social in character. In one clear sense then, human lives are not separate at all, but connected, in the sense that any plan of

    So therefore my prediction is that copper will be the best thermal conductor. Method 1. Collect 1 clamp stand, 1 stopwatch, some jelly, one each sample material, 1 nail and a Bunsen burner. 2. Setup clamp stand, place one of the sample materials in the clamp and close in tightly.

  2. Investigation into the physical properties of glass.

    This cools the surface but leaves the middle hot. When the middle cools it contracts, the surface contracts with it, meaning that the surface has contracted twice and is now under compression. To break the glass this compression must first be overcome.
