Which of the following has the strongest interparticle force of attraction between its particles at room temperature?
Which of the following has the strongest interparticle force of attraction between its particles at room temperature?
The correct option is C Iron
As we know, more the distance between the particles, lesser is the force of attraction between them. We also know that the distance between the particles in a gaseous substance is more than that of a solid.
1. Nitrogen is a gas at room temperature. So, it's particles have more space and less attraction between them than a solid.
2. Mercury is liquid at room temperature. So, it's particles have comparatively more space and less attraction between them, than a solid. However, it's particles have less space and more attraction in between them as compared to gases.
3. Chalk piece can be easily broken because it's particles have weak forces of attraction than that of iron.
