Can wires be made of coal?
Since coal is non-metal, it lacks the property like malleability and ductility. … So coal cannot be drawn into wires and sheets.
Why can we see wire made up of aluminum and copper but not of coal or wood?
Q7: Why we can see wires of aluminium and copper but not of coal or wood? Ans: Because wires of aluminium and coppers are made on the basis of property of metals called ductile, since wood and coal are non-metals and they dont show this property so it is not possible to make wires of these materials.
Why can’t we draw wires from a piece of Sulphur or coal?
and as the Sulphur and coal are the non metal, they are brittle not come in used to make wire….
Can we draw a wire from a piece of wood or coal?
(a) draw wires from a piece of wood or coal (b) use nylon or jute ropes for electrical transmission (c) use a cooking utensil made of cardboard Answer: (a) We cannot draw wires from a piece of wood or coal because they are brittle. They break down on stretching.
Is coal a ductile metal?
Reason: – As coal is a non-metal, so it is non-ductile. Question 5: Some properties are listed in the following Table. Distinguish between metals and non-metals on the basis of these properties.
Can Call drawn into wires?
Materials which can be drawn into wires are called ductile.
Why can copper be drawn into wires?
Copper is a ductile metal. This means that it can easily be shaped into pipes and drawn into wires. Copper pipes are lightweight because they can have thin walls. They don’t corrode and they can be bent to fit around corners.
Is Sulphur dull or shiny?
Appearance and Hardness of materials
|Coal||Dull||Not very hard|
|Sulphur||Dull||Not very hard|
Can sulphur be used to draw wires?
As sulphur is a non-metal, so it is not ductile (cannot be drawn into wires). … Therefore it cannot be used to make wires.
Can sulphur be drawn into wires?
As sulphur is a non metal and non metals are brittle so it can not be drawn into wires.
