Question

23.A piece of chalk can be broken in to small pieces when hammered but it is not possible in case of iron bar.
Vhich characteristic is illustrated by this observation?​

Answer 1

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.
