Question

7. A piece of chalk can be broken into small particles on hammering but it is not possible to do
so in case of a piece or a bar of iron. Explain.
please answer only if you know about the answer ​

Answer 1

Answer:

Since in chalk the particles forces between the chalk particles are not so strong hence they can be easily broken up while the interparticle distance between the particles of iron is strong as there are strong metallic bonds between them. Hence they cannot be easily broken down.

Explanation:

mark me brain list thank you

Answer 2

Here the intermolecular forces of attraction between the particles are identified or mentioned. Since in chalk the particles forces between the chalk particles are not so strong hence they can be easily broken up while the interparticle distance between the particles of iron is strong as there are strong metallic bonds between them. Hence they cannot be easily broken down.
