Question

a piece of chalk can be broken into small particles on hammering, but it is not possible to break a piece of iron in the same fashion. why?

Answer 1

Hey!

____________________

Question arises that both chalk and iron are solids and we know that solids can't be broken easily, but we can easily break a piece of chalk, how?

Well, Answer is just because of forces of attraction. Force of attraction between particles of chalks is less than force of attraction between particles of iron and because of weak forces of attraction in chalk piece, we are able to break it easily and it's difficult to break a piece of iron.

Answer 2

Explanation:

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.
