Aluminium is used for making cooking utensils. Which of the following properties of aluminiumare responsible for the same?(i) Good thermal conductivity (ii) Poor electrical conductivity(iii) Not Ductile (iv) High melting point(a) (i) and (ii) (b) (i) and (iii)(c) (ii) and (iii) (d) (i) and (iv

The correct answer is (d) (i) and (iv).

Step 1: Understand the properties of Aluminium Aluminium is a metal that is known for its good thermal conductivity and high melting point.

Step 2: Relate the properties to the use When it comes to cooking utensils, good thermal conductivity is a desirable property because it allows for even heat distribution. This means that food will cook evenly.

The high melting point of aluminium is also important because cooking utensils are exposed to high temperatures. If aluminium had a low melting point, it would melt under these conditions, which is not desirable.

Step 3: Eliminate the incorrect options We can eliminate options (a), (b), and (c) because they include properties that are not relevant to the use of aluminium in cooking utensils. Aluminium is not poor in electrical conductivity, in fact, it is a good conductor of electricity. Also, aluminium is ductile, which means it can be drawn into thin wires or sheets, but this property is not particularly relevant to its use in cooking utensils.

Therefore, the correct answer is (d) (i) and (iv).
