So here in this question we need to name the crystalline solids for the following conditions.
00:06
So the first one that we have is a material that can be melted and reformed at a low temperature.
00:13
So the answer for this is a molecular solid.
00:21
Now let us understand why we have chosen molecular solid as the answer for this.
00:26
So in molecular solid, they are held together by the weak, van, and the walls forces.
00:40
And so it is easy to break them and we can write that they are melted easily and then again reformed at a low temperature when the kinetic energy of the molecules is sufficiently reduced.
01:01
So we have solved part a.
01:04
Now let us move on to part b.
01:05
So here we have to name a material that can be drawn into thing long, wires.
01:11
So the answer for this part is a metallic solid.
01:20
This is because the metallic solid they have the property of ductility where they can be drawn into wires.
01:36
So the answer for part b is solved.
01:40
Next let us move on to part c.
01:42
So here we have to name a material that conducts electricity when molten.
01:47
So the answer for this part is an ionic solid...
