Aluminium is used for making cooking utensils. Which of the following ...
Introduction
Aluminium is a widely used material for cooking utensils due to its unique properties. The question focuses on identifying which properties make aluminium suitable for this purpose.
Key Properties of Aluminium
- Good Thermal Conductivity
- Aluminium has excellent thermal conductivity, which allows for even heat distribution.
- This ensures that food is cooked uniformly without hot spots, making cooking more efficient.
- Good Electrical Conductivity
- While aluminium is a good conductor of electricity, this property is not particularly relevant to cooking utensils.
- Electrical conductivity is more important for applications like wiring and electronics.
- Ductility
- Aluminium is highly ductile, meaning it can be easily shaped into various forms.
- This property allows manufacturers to create lightweight and strong cooking utensils in various designs.
- High Melting Point
- Aluminium has a melting point of about 660°C, which is relatively high.
- This makes it suitable for cooking, as it can withstand high temperatures without melting or deforming.
Conclusion
The correct answer to the question is option 'A' because:
- Good thermal conductivity (i) is essential for efficient cooking.
- Ductility (iii) is important for the manufacturing of various utensil shapes.
While properties like electrical conductivity and high melting point are noteworthy, they do not significantly contribute to the effectiveness of aluminium in cooking utensils. Therefore, options (i) and (iii) are the primary reasons for aluminium's popularity in this context.
