Question

Copper is good .............. Plastic is an ...............

Answer 1

Copper is a chemical element with the atomic number 29 and the symbol Cu (from Latin: cuprum). It's a ductile, malleable metal with excellent thermal and electrical conductivity. A freshly exposed pure copper surface is pinkish-orange in hue. Copper is used as a heat and electricity conductor, a construction material, and a component of many metal alloys, including sterling silver for jewellery, cupronickel for maritime gear and coinage, and constantan for strain gauges and thermocouples for temperature monitoring.

Complete step by step solution:
Despite competition from alternative materials, copper is still the primary electrical conductor in virtually all types of electrical wire, with the exception of overhead electric power transmission, where aluminium is frequently used. Copper wire is utilised in a wide range of applications, including power production, transmission, distribution, telecommunications, electronics circuits, and a wide range of electrical equipment. The copper industry's most significant market is electrical wire. Structural power wiring, power distribution cable, appliance wire, communications cable, automobile wire and cable, and magnet wire are all examples of this type of wiring. Electrical wire and cable conductor’s account for almost half of all copper mined.
Insulators are materials that do not allow current to flow freely because they have almost no free electrons available for conduction processes like metals. Plastic, wood, and rubber are all nonmetal materials that act as insulators. Plastics are great insulators, which means they can effectively trap heat – a feature that might be useful in a coffee cup sleeve. However, this insulating feature is less desirable in items such as laptop and mobile phone cases, which might overheat due to the covers trapping the heat produced by the devices.

Note:
Copper wiring is used in a variety of electrical devices due to its many inherent advantages, including high electrical conductivity, tensile strength, ductility, creep (deformation) resistance, corrosion resistance, low thermal expansion, high thermal conductivity, ease of soldering, malleability, and ease of installation. Copper wire was replaced by aluminium wiring in many house development projects in America for a brief period between the late 1960s and the late 1970s. After a series of residential fires were linked to the new wiring, the industry went back to copper.
