Wire is typically made out of metal because metal is ductile and conducts electricity.
Ductility is the property of metal which makes it easy to be stretched into wire when drawn without breaking. This is a great feature for wires.
Conductor of electricity : The ability for a material to allow electricity to pass through it with ease shows it is a good conductor of electricity.This is also a great feature for wires.
The transition metal, copper is usually preferred for the manufacture of electrical wires This is because apart from being thermal resistant and cheap, it is very ductile and a good conductor of electricity.

What are some advantages and disadvantages to the acid rain management techniques?
Acid rain management techniques include protect plants from acid rain on falling on them.
What is acid rain?Rain formed when sulfur dioxide and nitrogen oxide react with chemicals in the atmosphere like water,oxygen and carbon dioxide to form sulfuric acid and nitric acid and then falling to ground containing these acids is called acid rain.
Acid rain alters the environment the environment tremendously by damaging plants and aquatic ecosystems.Plants require a specific pH of soil for their optimum growth and nutrition.
Due to acid rain, the acidity of soil increases rendering it unfit for plant growth.Similarly, pH of water also increases which affects the survival of aquatic ecosystems.
It also damages the the monuments made of metals, marbles .Taj Mahal made up of white marble has turned yellowish due to acid rain.
