surface area of the chalk when was not
broken and the case of the sum of the areas

Answer 1

Answer:

The chalk is powdered or strong

Answer 2

Answer:

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.
