Make a list of at least 5 objects made up of different metals. Record your observations. Also, make a report based on your observations. Your report should explain why a particular metal can or cannot be used for making other objects.
Answers
Answer:
Explanation:
COPPER:
Most copper is used in electrical equipment such as wiring and motors. This is because it conducts both heat and electricity very well, and can be drawn into wires. It also has uses in construction (for example roofing and plumbing), and industrial machinery (such as heat exchangers).
IRON:
It is used to manufacture steel and also used in civil engineering like reinforced concrete, girders, etc. Iron is used to make alloy steels like carbon steels with additives such as nickel, chromium, vanadium, tungsten, and manganese. These are used to make bridges, electricity pylons, bicycle chains, cutting tools, and rifle barrels. Cast iron contains 3–5% carbon. It is used for pipes, valves, and pumps. Iron catalysts are used in the Haber process for producing ammonia. Magnets can be made of this metal and its alloys and compounds.
GOLD:
Dentistry and Medicine: Gold is considered as the best filling for cavities and crowns, bridges, and other orthodontic appliances because the metal is ductile and can easily take shapes.Electronics and Computers: Medals and Statues: Jewellery.
SILVER:
It is used for jewelry and silver tableware, where appearance is important. Silver is used to making mirrors, as it is the best reflector of visible light known, although it does tarnish with time. It is also used in dental alloys, solder and brazing alloys, electrical contacts, and batteries.
STAINLESS STEEL:
Stainless steel is ideal for hygienic environments as it's easily sterilized and resistant to corrosion. It is used in the construction of surgical and dental instruments, kidney dishes and operating tables, as well as other medical equipment such as cannulas, steam sterilizers, and MRI scanners
