The usage of metallic and non metallic substances in our households, are as follows -
- Metallic substances :
- Copper metal is used to make the internal part of the household electrical wire which conducts the electricity. Here, metal is used because metal is a good conductor of electricity.
- Iron and aluminium are used to make the cooking utensils of the household. Here, metal is used because metal is a good conductor of heat energy.
- Non metallic substances :
- Wood is used to make the household furnitures because wood is durable and much more light weight than the most of the metals.
- Curtains are made out of different fabrics due to the softness, light weight and extreme flexibility of the fabric material.
