In the simple model of the three states of matter, the particles are represented by small solid spheres. Which of these is a limitation of this simple model?
The model shows the particles in a solid in a regular pattern
The model shows no forces acting between the separate particles
The model shows the particles moving faster at a higher temperature
The model shows the particles in a solid as being very close together
