Copper Research.

Extracts from this document...

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.

  1. The task has been set to make a hole punch (used to punch holes ...

    This problem could be overcome by brazing the two components or using caphead screws or nuts and studs if a temporary fixture was preferred. Because the handle is so big it too will be very heavy, this means that the spring beneath the punch will need to be very strong

  2. My aim of this experiment is to recognize which material is the greatest sound ...

    this means the sound waves will not be able to easily travel through the material. As the layers are added on to the existing layer right up to the third layer I deem that the amount of sound will vastly decrease each time, as the sound will become more and

  1. EFFECT OF MOISTURE ON THE MECHANICAL PROPERTIES OF NYLON

    Another dominant feature of Nylons is crystallinity. As with most crystalline polymers, the molecular chains are uncluttered by large substituent groups. They are flexible and regular in-group spacing and crystallize readily. As with acetals, this crystallinity is responsible for properties of wear resistance, chemical resistance, thermal resistance, and unfortunately, higher mold shrinkage.

  2. Investigation into the physical properties of glass.

    Light is electromagnetic radiation and its electric field distorts the electron cloud of the adjacent atoms. This is polarisation. As a result of the polarisation a proportion of the energy may be absorbed, transmitted or absorbed and immediately re-emitted at a different speed.

  1. Thermal Conductivity.

    Place the Bunsen burner to one of the clamp stand. 4. Put the nail in some jelly and place onto the sample material that of which is at the opposite end to the Bunsen burner. 5. Alight the Bunsen burner and start the stopwatch.

  2. In this investigation I aim to find out which materials are the best insulators. ...

    The results suggest that my prediction was correct. When comparing the results of the insulating materials to those of the control, we can see that the carpet is the most efficient material for reducing heat loss. The yellow line is the highest on the graph, suggesting that my original prediction was correct.

    the CAD cam machine I used vinyl as this would make the train stand out more and would make it more eye catching. But everything else was exactly the same as what it said in the specification; except for the modifications and adjustments that had to be made to the

  2. TENSILE TESTING OF METALS

    stress is the stress at which plastic deformation is likely to become more apparent. The yield stress in steel for example is at that stress at which the steel no longer behaves elastically and suffers irrecoverable elongation. If the yield strength is exceeded the object will be permanently deformed and
