why we didnot draw wires from a peice of wood
Answers
Solution :-
We cannot draw wires from a piece of wood because wood is not a metal and it does not have the property of ductility. Ductility is a physical property of a material associated with the ability to be stretched into wires without being broken. A ductile substance can be drawn into wires.
Most metals are good examples of ductile materials. Some examples of ductile metals are gold, silver, copper, erbium, terbium, and samarium. An example of a metal that is not very ductile is aluminium but wires are made from aluminium. Non-metals are generally not ductile.
If we talk about a piece of wood, then we know the following properties about it:
1. It is an insulator of electricity or we can say that it is a bad conductor of electricity
2. It is not malleable i.e. it can not be hammered such that it gets converted into a sheet.
3. It is not ductile i.e. it cannot be used to form wires.
4. It is porous to certain extent.
5. It is a bad conductor or an insulator of heat.
The most important characteristics which we usually require to make wires are conductors of electricity and ductility.
Now, we see that none of these properties are present in a piece of wood, hence we do not draw wires from a piece of wood.
