The motion of particles in different states is difficult to observe. A student used computer software to represent the movement of particles in the solid state. Which type of scientific model did the student use?



A simulation because it imitates an intrinsic process in the molecule.


A simulation because it helps visualize the orientation of atoms in the molecule.


A 3-dimensional model because it helps visualize the orientation of atoms in the molecule.
