2.1.2 State THREE properties of copper.
Answer
Copper possesses several notable properties:
- Excellent conductor of electricity – Copper is widely used in electrical wiring due to its high conductivity.
- Ductility – It can be easily drawn into wires or shaped into various forms.
- Resistance to corrosion – Copper does not rust and can withstand environmental factors.
Step 3
2.1.3 Describe TWO requirements that determine the composition of brass.
Answer
The composition of brass is determined by several requirements, including:
- Manufacturing requirements – This pertains to the desired mechanical properties that the final product should exhibit.
- Application requirements – This includes the specific usage of the brass component, such as whether it will be subjected to friction, stress, or corrosion.
Step 4
2.1.4 State THREE properties of tin.
Answer
Tin has several distinctive properties:
- Silvery-white appearance – Tin has a lustrous finish that is visually appealing.
- Malleable – It can be easily shaped or compressed without breaking.
- Resistance to corrosion – Tin does not rust, which makes it suitable for coating other metals to prevent degradation.
