Question

3. Match the following
A
1. Bauxite ( ) a, non conductors of
electricity
2 mica ( ) b, roof sheets
3 chrome ( ) c aluminium
4 asbestos ( ) d wash basin
5 feldspar ( ) e stainless steel​

Answer 1

Answer:

1. aluminium

2. non conductors of electricity

3. stainless steel

4. roof sheets

5. wash basin

Answer 2

Answer:

1) Bauxite -  (C) Aluminium,

2) Mica - (A) Non conductors of electricity,

3) Chrome - (E) Stainless steel,

4) Asbestos - (B) Roof sheets,

5) Feldspar - (D) Wash basin

Explanation:

• Bauxite is the main ore of aluminium (aluminum). It is comprised of primarily impure aluminium hydroxides with a lot of silica, iron and other impurities.
• Due to its high thermal resistance, mica is an excellent industrial insulation material that is a non conductor of electricity.
• Chrome plating steel is a special type of steel that has been combined with chromium with the aim of preventing rusting.
• Asbestos cement are used as roofing sheets which are rust & rot resistant and can also protect them from chemical attack.
• Feldspars play an important role as fluxing agents in ceramics and glass applications, used primarily for wash basins.
