Question

select the correct answer. an iron nail is made up of particles. what is true about the particles? a. they move all over the place. b. the force of attraction between them is small. c. the spacing between them is large. d. they stay in place and vibrate.

Explanation:

An iron nail is a solid. In solids, particles are closely packed, have strong attractive forces, and vibrate in fixed positions (don't move freely like in liquids/gases, spacing is small, and attractive force is large). Option A is for gases/liquids, B is incorrect (attractive force in solids is large), C is incorrect (spacing in solids is small). So D is correct as solid particles stay in place and vibrate.

Answer:

D. They stay in place and vibrate.
