Question 5

What describes the arrangements and movements of the particles in solids, liquids, and gases?

Answer 5

Particle model.

Question 6

How are the particles in solids arranged? Can they move freely?

Answer 6

They are close together and arranged regularly. They cannot move from one position to another but can vibrate about fixed positions.

Question 7
