Answer 1

The particles are held together with greater force in the iron nail bcoz it's somewhat hard to break them as they are having more force of attraction between its particles. Hope this helps you and pls mark as brainliest

Answer 2

Iron holds the particle with greater force.

Explanation:

Iron will not break when it is hammered because the molecules of the iron are held together with such a greater force. It will impossible to break iron with simple hammering. But it can be broke when it is hammered at high temperatures. Let us consider the case of chalk piece and rubber, where the chalk piece can be easily cut and the rubber can be cut when it is stretched because their molecules are packed together loosely when compared to the iron nail.
