Question

Answer 1

Answer:

because aluminum has a high melting point and is a great conductor that copper

Answer 2

Answer: Aluminium is preferred because it can protect copper from being attacked by rust i.e. losing its lusture after coming in contact with the open atmosphere (mainly oxygen) . Also rusted copper is much harmful for daily uses as cooking utensils.

Explanation:

In the electromagnetic series aluminum is placed in a lower position with respect to copper and as it's known metals placed at higher positions in electromagnetic series are highly reactive & metals placed at lower positions are less reactive - so copper being highly reactive can be affected by rust if kept un-electroplated by any low reactive metal.So aluminum being less reactive is electroplated over copper cooking utensils so that utensils might not get affected by rust and not harm living beings.
