ductile : A material that can be drawn into wires. malleable: Means that the material can be hammered into very thin sheets without breaking.
Which of the following can be drawn into thin wires?
Metals can be drawn into thin wires. Aluminium is a metal in which the given elements have ductility. A material that can be stretched thin when tensile stress is applied is called to be ductile and the property is known as ductility .
Which can be drawn into wires?
Some metals like gold can be drawn out into wires or beaten into sheets only a few atoms thick and still retain their strength. Copper, gold, iron, silver and aluminium are used extensively in flat sheets, foil, and wire because they are highly malleable and ductile.
What materials Cannot be converted into wires?
Non-metals cannot be converted into wires. 4. The only liquid metal is bromine.
Why is that silver is not drawn to be used in wires?
Though silver is a very good conductor of electricity but still that is not used in electric wiring primarily due to its cost. It’s very expensive compared to the widely used wiring material copper. Another reason for not using silver is that , it oxidizes easily and tarnishes when it comes in contact with air .
Can we convert it into wires?
A metal is an element that is a good conductor of heat and electricity. Metals are also malleable, which means that they can be hammered into very thin sheets without breaking. They are ductile , which means that they can be drawn into wires.
Can copper be drawn into wires?
Some metals like gold can be drawn out into wires or beaten into sheets only a few atoms thick and still retain their strength. Copper, gold, iron, silver and aluminium are used extensively in flat sheets, foil, and wire because they are highly malleable and ductile .
Can iron be drawn into wires?
Some metals like gold can be drawn out into wires or beaten into sheets only a few atoms thick and still retain their strength. Copper, gold, iron, silver and aluminium are used extensively in flat sheets, foil, and wire because they are highly malleable and ductile .
What is the most conductive metal on earth?
Silver has the highest electrical conductivity of all metals. In fact, silver defines conductivity – all other metals are compared against it. On a scale of 0 to 100, silver ranks 100, with copper at 97 and gold at 76.
What is the best conductor of electricity list?
| 1 Silver (Pure) | 2 Copper (Pure) | 3 Gold (Pure) | 4 Aluminum | 5 Zinc |

Why Aluminium is not used in electric wires?
Most metals (with a few exceptions, such as gold) oxidize freely when exposed to air. Aluminium oxide is not an electrical conductor, but rather an electrical insulator . Consequently, the flow of electrons through the oxide layer can be greatly impeded.
Can be drawn into wires answer key?
Answer: A material that can be drawn into wires. malleable : Means that the material can be hammered into very thin sheets without breaking. metal: An element that is a good conductor of heat and electricity.
Can iodine be drawn into wires?
Nonmetals can be gases (such as chlorine), liquids (such as bromine), or solids (such as iodine) at room temperature and pressure. Most solid nonmetals are brittle, so they break into small pieces when hit with a hammer or pulled into a wire.
Which of the following is a property because of which material can be drawn into wires?
ductile : A material that can be drawn into wires. malleable: Means that the material can be hammered into very thin sheets without breaking.
Why is copper a preferred choice in making electrical wires?
Why is copper used for most electrical wiring? ... The lower the level of resistivity, the more electrical conductivity a metal has. Copper has low resistivity, and therefore is an excellent conductor. Copper is also less oxidative than other metals.
What does drawn into a wire mean?
wire•draw. ... 1. to draw (metal) out into wire, esp. by pulling forcibly through a series of holes of gradually decreasing diameter in a succession of dies. 2. to draw out to great length, in quantity or time; stretch out to excess. 3. to strain unwarrantably, as in meaning.
