Worked Solution & Example Answer:i) What property of Cu makes it suitable for use in electrical wiring? ii) What property of Au makes it suitable for use in jewellery? - Junior Cycle Science - Question f - 2017
Step 1
What property of Cu makes it suitable for use in electrical wiring?
Answer
Copper (Cu) is a good conductor of electricity due to its high electrical conductivity. This means that it allows electric current to flow through it easily, which is essential for electrical wiring. Additionally, copper is ductile, which means it can be drawn into thin wires without breaking, making it ideal for various wiring applications.
Step 2
What property of Au makes it suitable for use in jewellery?
Answer
Gold (Au) is suitable for use in jewellery primarily because it is unreactive, meaning it does not tarnish or corrode easily. This property ensures that gold maintains its luster and appearance over time. Furthermore, gold is malleable and ductile, allowing it to be shaped into intricate designs and forms, making it an excellent material for fine jewellery.
