Question
Select the element that you would choose to make overhead power lines from the list below.SodiumSilverPotassiumAluminium
Solution
The best choice for making overhead power lines from the list provided would be Aluminium.
Here's why:
-
Sodium and Potassium are both highly reactive metals. They react violently with water and oxygen in the air, which makes them unsuitable for outdoor use like overhead power lines.
-
Silver, while being the best conductor of electricity, is very expensive and not practical for such large-scale use.
-
Aluminium, on the other hand, is a good conductor of electricity, is less expensive than silver, and does not react violently with water or oxygen. It is also lightweight which makes it ideal for overhead power lines. Therefore, Aluminium would be the best choice from the list provided.
