please give the answer for class 8
Answers
Answer:
The property by which metal can be beaten into sheets is called malleability
The property of drawing a metal into thin wires is called ductility
A material is brittle if, when subjected to stress, it fractures with little elastic deformation and without significant plastic deformation.
liquid metal: mercury
non-metal liquid: bromine
Example of non-metal are:
Chemical element.
Carbon.
Nitrogen
Example of metal are:
aluminum
copper
iron
umm sorry don't know the q-4
please then also mark me brainiest✨
Answer:
Q1)
- Malleability :- The property of metals by which they be beaten into
thin flat sheets.
For example,
Aluminium can be beaten into thin sheets to make aluminium foil.
- Ductility : - The property of metals by which they can be drawn
into thin wires.
For example,
Copper can be drawn into thin wires as they are good conductors of
electricity.
- Brittleness :- The property of non-metals by which they can break
into several pieces when beaten hard unlike metals
which get flattened when the same happens to it.
