• 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.
